This Code Share Agreement is made as of May 3, 2001, by and between Frontier Airlines, Inc. ("Frontier"), a Colorado corporation and
Great Lakes Aviation, Ltd. ("Great Lakes"), an Iowa corporation.

A.       Frontier and Great Lakes are each operating, certificated air carriers providing air transportation services in their
         respective areas of operation.

B.       Frontier and Great Lakes desire to engage in joint marketing activities designed to increase the flow of air passenger
         traffic on aircraft operated by both parties.

C.       Frontier and Great Lakes desire to cooperate in the coordination of schedules by allowing Great Lakes to market its flight
         operations under the "F9*" designator.

         NOW, THEREFORE, in consideration of the premises and the mutual promises herein contained, Frontier and Great Lakes hereby
agree as follows:

international taxes and charges, sales taxes, segment taxes and fees, use taxes, stamp taxes, excise taxes, value added taxes, gross
receipts taxes, departure taxes, surcharges and travel taxes, and all related charges, fees, licenses or assessments (and any
interest or penalty thereon) imposed on passengers (or which air carriers or their agents are required to collect from passengers) by
any authority in any country, or political subdivision thereof or public authority operating therein (including, without limitation
any national, federal, state, provincial, territorial, local, municipal, port or airport authority) or which are levied upon
passengers by operation of applicable law or industry standard.  Ticket Taxes together with the taxes referred to elsewhere in

operated by Frontier will utilize the designator code F9* ("Code Share Flights").  The parties shall meet together as often as is
mutually agreed during the period this Agreement is in effect to discuss the appropriateness of expanding or contracting the list of
city pairs on Exhibit A.  Flights covering an origin and destination market that is created by an F9* Code Share Flight connecting to
a Frontier flight operated by Frontier are hereinafter referred to as "Through Flights."  Except as expressly set forth herein,
neither party shall have any obligation to extend Frontier or Great Lakes flights to other routes or to maintain operations on any
routes and no such obligation can be created by any oral statements or representations or course of dealing by a party, but only by
an express written agreement.

(2)  Procedures Manual.  As a guide to the implementation of this Agreement, the parties will prepare a Procedures Manual, which may
be modified from time to time, containing detailed procedures regarding the operation of this Agreement.  The parties agree to
complete and agree on the initial Procedures Manual no later than 45 days before the first date that a Codeshare Flight is conducted
(the "Implementation Date"), as defined in this Agreement.

(3) Conditions of Carriage.  The Terms and Conditions of Contract of Carriage of Frontier Airlines shall govern the transportation of
Code Share Passengers.

         (a)      The parties will use existing IATA procedures when handling and settling claims made by customers in connection with

Section 3.  Confidential Information

(1)  Except as set forth below, and except in any proceeding to enforce any of the provisions of this Agreement, neither Frontier nor
Great Lakes will, without prior written consent of the other, use, publicize or disclose to any third party, either directly or
indirectly, any of the following (hereinafter "Confidential Information"):

     (a)  this Agreement or its terms or conditions
     (b)  Any confidential or proprietary information or data, either oral or written, received from
          and designated as such by the disclosing carrier.

(2)  If either carrier is served with a subpoena or other legal process requiring the production or disclosure of any Confidential
Information, then that carrier, before complying, will immediately notify the non-disclosing carrier so the non-disclosing carrier
shall have a reasonable period of time to intervene and contest disclosure or production if the non-disclosing carrier so chooses.
If a governmental authority requests either Frontier or Great Lakes to produce or disclose to the authority this Agreement or any of
the terms or conditions of this Agreement, or if any governmental regulatory agency (e.g., Securities and Exchange Commission or
Department of Transportation) requires the production or disclosure of this Agreement or its terms, such carrier may produce or
disclose the requested document or information.

(3)  If any financial institution requests or requires production or disclosure of this Agreement or its terms or conditions, in
connection with a current or proposed financing, Frontier or Great Lakes may produce or disclose this Agreement provided the
financial institution agrees to keep the disclosed material and information confidential.

Section 4.  Code Sharing License

(1)  Grant of License.  Subject to the terms and conditions of this Agreement, Frontier hereby grants to Great Lakes a nonexclusive,
nontransferable, revocable license to use the F9* designator code on all its flights operated as Code Share Flights.  Frontier agrees
to not grant a license to use its F9* designation code or any other code or service marks to any other carrier for use in Code Share
Service in markets set forth in Exhibit A, hereto, as may be supplemented or amended from time to time.

(2)  Service Marks.  Great Lakes shall have a nonexclusive, nontransferable, revocable license to use the Frontier Service Marks (as
defined below) in its marketing programs for the purpose of promoting F9* Flights. All advertising programs using Frontier Service
Marks shall be subject to Frontier's prior approval.  In general, Great Lakes' use of the Frontier Service Marks shall do no more
than identify the code share relationship between Great Lakes and Frontier and advertise that schedules are coordinated to provide
convenient connections.  Any marketing program, advertising brochures, schedules, signs or information disseminated to the public or
intended to be disseminated to the public ("Advertising Material") shall reflect that Great Lakes and Frontier are operated
separately and shall comply with any DOT policy on airline designator code sharing.

(3)  Great Lakes is specifically prohibited from using any of the Frontier Service Marks on its aircraft or other equipment, on its
stationary, or elsewhere unless Great Lakes has received prior specific authorization in writing from Frontier.  Great Lakes hereby
acknowledges Frontier's exclusive ownership of the Frontier Service Marks and agrees that it will not do anything that would
infringe, abridge or adversely affect, impair or reduce the value or validity of the Frontier Service Marks.  In no event shall Great
Lakes allow the use of any Frontier Service Marks in marketing, selling, promoting or otherwise identifying or referencing any flight
which is not an F9* Flight. Frontier hereby grants to Great Lakes a nonexclusive, nontransferable, revocable license to use the name
Frontier and its service marks in Great Lakes marketing programs, for the purpose of promoting the F9* Flights.  As used herein the
term "Service Marks" shall include, without limitation the Frontier designator code, various trademarks, service marks and logos.

Section 5.  Sales and Marketing Programs

The parties will work to develop mutually agreeable joint sales and marketing programs to help promote the code share relationship

marketing programs and strategies.

Section 6.  Schedules and Flight Display

(1)  Schedule Filing.  Frontier and Great Lakes shall coordinate the filing of schedules with the Official Airline Guide ("OAG") (and
any other airline guide or schedule as mutually agreed) for Through Flights.  To facilitate the schedule filing process, Frontier and
Great Lakes shall supply to each other the necessary detail in writing in sufficient time to meet applicable filing deadlines, but in
no case less than 45 calendar days prior to the effective date of the schedule (or notice as far in advance as possible if 45 days is
impracticable).  A separate set of consecutive Frontier flight numbers will be assigned to Great Lakes for F9* designated flights
operated by Great Lakes.

(2)  Flight Display.  All Through Flights will be included in the availability and fare displays of all computerized reservations
systems in which Frontier and Great Lakes participate, the OAG (to the extent agreed upon) and Frontier and Great Lakes internal
reservation systems under the F9* designator code.  Frontier and Great Lakes will take the appropriate measures necessary to ensure
the display of Through Flights in accordance with the preceding sentence.

         (a)      Frontier and Great Lakes will disclose and identify the Great Lakes flights utilizing the F9* designator code to the
                  public as actually being flights of and operated by Great Lakes, in at least the following ways:

                  (i)      a symbol will be used in timetables and computer reservation systems indicating that F9* Flights are
                           actually operated by Great Lakes;

                  (ii)     to the extent reasonable, messages on airport flight information displays will identify the operator of
                           flights shown as F9* Flights;

                  (iii)    Frontier and Great Lakes advertising concerning F9* Flights and Frontier and Great Lakes reservationists will disclose the
                           operator of each flight; and,

                  (iv)     in any other manner prescribed by law.

(3)  Flight Information.  Great Lakes shall use reasonable efforts to keep current flight following information for F9* designated
flights operated by Great Lakes for display in the Frontier reservation system.  This information shall be updated regularly by Great
Lakes.

(4)  Changes of Service.  Each party shall give the other party 60 days advance written notice (or notice as far in advance as
possible if 60 days is impracticable) of any intended material changes to (a) its operating specifications, or (b) to the manner of
conducting its business or the nature of its product as it relates to its operations at Denver, Minneapolis/St. Paul, or Phoenix.  In
the event any such change has an adverse material change to the value or risk to the other party of this Code Sharing Agreement in
the other party's judgement, the other party shall be entitled to terminate this agreement if the change is implemented.

Section 7.  Pricing and Capacity Control of Code Shared Segments

(1)  Pricing.  Frontier and Great Lakes shall jointly establish and set fares for Through Flights.  Frontier shall have no authority
to establish or set fares for Great Lakes Flights.  If no fare is set for a Through Flight, the fare for such Through Flight will be
the sum of each carrier's segment fares.

(2)  Tariffs.  For F9* Code Share Service, Frontier and Great Lakes shall develop jointly (consistent with each Carrier's other
preexisting code share relationships) those conditions of carriage and tariff rules that need to be uniform in order for the Code
Share Service to be provided in a seamless manner.  Such rules governing the air transportation provided as part of a F9* Code Share
Service shall be available for public inspection at Frontier's and Great Lakes' corporate offices, at each airport ticket office, and
at each city ticket office maintained and operated by Frontier or Great Lakes in the manner required by DOT regulations.

(3)  Each Carrier will have access to the other Carrier's inventory through an automated computerized interface which both parties
will maintain throughout the term of this Agreement to expedite the sale of inventory on the Code Share Flights.

(4) The parties will map inventory classes of Frontier flights to inventory classes of Great Lakes flights on the Code Share Flights
by mutual agreement.  The parties will endeavor to map the average coupon value of Frontier's inventory classes to comparable classes
of Great Lakes to provide nondiscriminatory access for bookings made by each carrier for passengers yielding comparable revenue
values; it being understood, however, that the Operating Carrier retains ultimate control over the opening, closing, and other
management of seat inventory availability on Code Share Flights.

(5)  Each carrier will be able to book Code Share Passengers up to the same maximum seat inventory per booking class (including
authorized overbooking) available to the other carrier for a Code Share Flight, provided that such seats may be available for sale on
an equal basis under other designator code(s).

(6)  Frontier and Great Lakes will each assign one or more individuals to serve as inventory control coordinators, who will, to the
extent permitted by applicable law, exchange information routinely and conference as necessary to assure that reasonable seat
inventory on Code Share Flights is made available.

Section 8.  Quality of Service

Great Lakes shall perform its service in a timely, expert and quality manner. Great Lakes shall maintain its aircraft in an
airworthy, clean, attractive and comfortable condition and will maintain a completion factor of at least 97% (excluding cancellations
caused by air traffic control, weather, or force majeure) in its F9* operations or meet the performance standards as reported by
Frontier for the same period, whichever is lower.  Great Lakes will, in conducting F9* Flight operations, employ prudent safety and
loss prevention policies.

Section 9.  Control of F9* Flights

Great Lakes shall have sole responsibility for and control over, and Frontier shall have no responsibility for, control over or
obligations or duties with respect to, each and every aspect of Great Lakes operations including, without limitation, scheduling
(except as provided in Section 6 hereof); pricing (except as provided in Section 7 hereof); planning of flight itineraries and
routings; reservations; reservations control/yield management; dispatch; fueling; weight and balance; flight release; maintenance;
and flight operations and compliance with applicable rules and regulations.

Section 10.  Aircraft and Crews

Frontier and Great Lakes will provide the scheduled air service that is part of F9* Code Share Service in full compliance with FAA
regulations applicable to scheduled air service.  Flights operated by Frontier shall be operated by its aircraft and crews and
Flights operated by Great Lakes shall be operated by its aircraft and crews.  Each party may utilize "wet" leases if mutually agreed
upon prior to operation of the aircraft on flights using the F9* Code Share designation.

Section 11.  Ground Support for Code Share Services

(1)      Great Lakes Cities.  Great Lakes will provide to passengers traveling on Great Lakes flights using F9* Code Share Service
         passenger check-in at each of the stations specified in Exhibit A.  To the extent reasonably feasible, passenger check-in
         and handling procedures will be provided in accordance with mutually agreed operating procedures.  Frontier and Great Lakes
         will jointly develop a method of providing Great Lakes' stations with assistance in check-in and ticketing of Code Share
         Passengers.  Frontier will provide to Great Lakes, at no cost to Great Lakes, the necessary familiarization training in
         Frontier's procedures.  Great Lakes shall arrange for Frontier identification to be prominently displayed at check-in
         counters and gate areas as appropriate at each of Great Lakes' stations where F9* designated Great Lakes flights are
         operated.  Such signage shall be at least equal in prominence to that of any other airline graphics, excluding Great Lakes,
         displayed at such Great Lakes stations.  Frontier, at its cost will develop and provide standardized signage material
         subject to Great Lakes approval. Such signage may be modified as necessary to conform to local station requirements for
         display at all Great Lakes stations described in Exhibit A.  The parties agree to cooperate to accomplish the objectives set
         forth in this paragraph as quickly as is reasonably feasible; provided, however, that completion of the obligations set
         forth in this paragraph are not conditions precedent to the effective date of this Agreement and the other obligations of
         the parties hereunder.

(2)  All Other Cities.  The parties intend to work to establish a convenient connection for passengers connecting from an F9* flight
to a flight operated by Frontier (or vice versa) while traveling on a Through Flight.  Frontier and Great Lakes will cooperate to
maximize the convenience of passengers who are connecting from a Great Lakes flight segment (or vice versa) on Through Flights.  Each
party will provide the other with the airport operational assistance that is required to assure schedule compatibility for Through
Flights.

(3)  Freight.  Frontier and Great Lakes will accept air freight and small package shipments for F9* Code Share Service to and from
points served by Frontier and Great Lakes Flights.  Documentation and handling procedures for such freight shall be consistent with
Frontier, Great Lakes and standard industry procedures.

(4)  Government Contracts.

         (a)  Frontier and Great Lakes shall each independently contract with the U.S. Postal Service for carriage of mail over their
         respective route networks.  The use of the F9* designator for F9* Code Share Service does not extend to the system mail
         contract rates between each carrier and the U.S. Postal Service.

         (b)  Each airline shall independently contract with the FAA, DOT or other governmental agencies with respect to all landing,
         departure and en route slots or other operational controls.  This Agreement will not affect any rights either airline has in
         current or future slots.

(5)  Flight Irregularities.  In the event of any flight cancellation or other schedule irregularity, involuntary rerouting or denied
boarding by the operating carrier with respect to any segment of Code Share Service, the operating carrier shall ensure that all
passengers shall be handled in accordance with the same policies and procedures to avoid any discrimination against a Code Share
Passenger.  It is the intent that the offending carrier shall pay the costs of such passenger accommodation.

         (a) at its own cost and expense, accommodate and/or pay denied boarding compensation or otherwise compensate Code Share
         Passengers, in accordance with the provisions of the Procedures Manual; and

         (b)  reimburse the non-offending carrier, in accordance with the Procedures Manual, for all reasonable costs incurred in
         connection with the compensation and/or accommodation of Code Share Passengers as a result of a schedule irregularity,
         involuntary rerouting or denied boarding as contemplated by this Section.  For the purposes of this paragraph only,
         "non-offending carrier" is defined as the operating carrier who delivers a Code Share Passenger to the connecting point at
         the agreed minimum connect time prior to the scheduled departure time of the other code share partner.

(6)  Baggage Claims.  Baggage handling and settlement of baggage handling claims shall be in accordance with existing tariffs and the
Trade Practice Manual of the Air Transport Association or the IATA Resolutions and Recommended Practices Manual, whichever applies.

(7)  Emergency Situations.  Frontier or Great Lakes as the case may be shall promptly notify the other carrier of all irregularities
involving one of its flights which result in any damage to persons or property as soon as such information is available and shall
furnish to the other as much detail as practicable.  For purposes of this section, notification shall be made as follows:

         To Frontier Dispatch
         To Great Lakes Dispatch

         (a)  Public Relations.  In the event of any irregularity in Great Lakes Flight operations, including, without limitation,
any event causing damage to persons or property, Great Lakes shall identify itself as being operated independently of Frontier and as
being solely responsible for its operations.  Great Lakes may state that it holds a code sharing license from Frontier and that it
obtains certain services from Frontier if third parties inquire as to such relationship.

Section 12.  Audit

Each Carrier shall have the right, at its own cost, to inspect, review, and observe the other carriers operations of Through Flights,
and/or to conduct a full safety and/or service audit of the other carriers operations, manuals and procedures reasonably related to
Through Flights, at such intervals as each carrier shall reasonably request.  In the exercise of such right, neither carrier shall
undertake any responsibility for the performance of the others operations.  Each carrier shall coordinate its safety and service
audits with the other so as to avoid disruptions of the other carriers operations.  Any safety audit may include, without limitation,
maintenance and operation procedures, crew planning, reservations, passenger and baggage handling, customer service, personnel
records, spare parts, inventory records, training records and manuals, flight training and operational records.  If a party desires
to establish the current economic viability of the other party and its financial capability to perform under this agreement, it may,
at its sole expense, request that the independent public accountant of the other carrier perform a review, but not an audit, of that
carriers financial position and receive a report thereon.

Section 13.  Reporting Obligations

(1)  Operations.  Frontier and Great Lakes shall provide each other with monthly written reports containing the following data for
Through Flights:

     (a)  the total number of scheduled and actual flights performed and cancellations by categories for the month, by market;

     (b)  completion and on-time performance data by system and market.  In addition, designated representatives of each carrier will
     meet monthly to review such reports and initiate action to improve performance as necessary.

(2)  Notice of Complaints.  Each carrier shall furnish monthly to the other carrier a summary of complaints, notices of violation,
requests to cease activity or similar correspondence which reasonably relate to Through Flights and which are received by the air
carrier from passengers, any government authority, or other parties.  Each carrier shall comply with the other carriers reasonable
requests for actual copies of any such documents.

(3)  Correspondence from Government Authorities.  Each Carrier shall immediately provide the other any copies of any correspondence
received from any government authority, which references (a) any alleged noncompliance with rules or regulations affecting air
transportation, or (b) any investigation performed or proposed by any government authority, including without limitation, any
communication issued by a government authority concerning the airworthiness of  aircraft, the compliance of the carrier's personnel
with required operational or training procedures or any other matter relating to the safe operation of the carrier's aircraft.

Section 14.  CRS Charges

Each carrier shall be responsible for its' own computer reservation systems costs.

(1)  Effective Date and Term

(a)      This Agreement shall become effective on the date first written above, or as soon thereafter as executed by both parties
              (the "Effective Date") and shall remain in effect continuously thereafter.  Either Great Lakes or Frontier may deliver
              to the other advance written notice of termination which notice provides for a termination date for this Agreement at
              least 180 days subsequent to delivery of the notice of termination (the "Termination Date"), provided that neither party
              may deliver such notice prior to the Implementation Date.

              (i)  In the event of a change of control of either carrier, in which the carrier is not the surviving carrier ("new

         Date if and when notice of termination is given.  The truncation shall be effected with the next normally scheduled
         transmission of schedule data to the various media.  The parties also agree that any code share passengers booked and
         ticketed for travel during the forward booking period while such code share service was published will be serviced in accord
         with operating procedures established by the parties pursuant to this Agreement, even though the Agreement may have been
         terminated subsequent to such booking and ticketing.

         insolvent; (ii) files a voluntary petition in bankruptcy; (iii) petitions for or acquiesces in the appointment of any
         receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets; (iv)

         readjustment of debt, dissolution, liquidation or any other similar proceeding for the relief of financially distressed
         debtors; (v) becomes the   object of any proceeding or action of the type described in (iii) or (iv) above and such
         proceeding or     action remains undismissed or unstayed for a period of at least sixty (60) days; or (vi) is divested of a
         substantial part of its assets so as to affect the ability to operate its business generally for a period of at least thirty
         (30) days; then the other party may by written notice terminate this Agreement immediately.

Section 23.  Default

(1)  Cure Period and Termination.  Except as otherwise provided herein, if either party shall default in performance of any of the
terms, covenants and conditions of this Agreement, the other party may give notice of such default to the party at default.  In the
event such default is not cured within (a) thirty (30) days after the giving of such notice or (b) five (5) business days in the case
of the failure to make any payments due and payable under the Agreement, the party giving notice may terminate this Agreement
effective upon such date that party specifies by further notice to the party in default, without prejudice to any other rights which
the other party may have.

(2)  No Waiver.  The waiver by either party of performance of any term, covenant or condition of this Agreement in a particular
instance shall not constitute a waiver of any subsequent breach or preclude such party from thereafter demanding performance thereof
according to the terms hereof.

Section 24.  Force Majeure, etc.

(1)  Neither party shall be liable to the other for any failure to comply with the terms of this Agreement or any loss, injury,
damage or delay whatsoever resulting, directly or indirectly, from one or more of the following: act of God; seizure under legal
process; governmental sanctions; quarantine restrictions; fire, fog, flood, or other weather-related reason; failure or refusal on
the part of any government or governmental agency to grant or issue approvals, clearances, exemptions, permits or operating
authority, or recession or revocation thereof by any government or governmental agency; damage to or destruction of aircraft or other
flight equipment; mechanical difficulties or breakdowns; unavailability of fuel; riots or civil commotion; strikes, lockouts or labor
disputes (whether resulting from disputes between either party and its employees or between other parties); U.S. military or airlift
emergency or substantially expanded U.S. military airlift requirements as determined by the U.S. government; activation of the U.S.
Civil Reserve Air Fleet; war or hazards or dangers incident to a state of war; or any other acts, matters or things, whether or not
of a similar nature, which are beyond the control of either party and which shall directly or indirectly, prevent, delay, interrupt,
or otherwise adversely affect the furnishing, operation or performance of such transportation.

(2)  Frontier or Great Lakes shall have the right to terminate this Agreement forthwith in the event of an airlift emergency as
determined by the United States Secretary of Defense or his designee or by the Commander of the United States Military Airlift
Command, or if the United States Civil Reserve Air Fleet is activated by order of the  Secretary of Defense, and, as a direct result,
Frontier scheduled service in Denver is reduced by 50%.

Section 25.  Taxes

(1)  Subject to Section 25(4), each party shall be responsible for any net or gross income or franchise taxes (or taxes of a similar
nature) on the revenues or income or any measure thereof which is attributable to it in connection with the sale of air
transportation pursuant to this Agreement.

(2)  The Ticketing Carrier, shall collect, except as otherwise prohibited by law, all Ticket Taxes relating to tickets sold or travel
documents issued by it with respect to air transport pursuant to this Agreement.  The parties hereby agree:

         (a)  The Ticketing Carrier, shall collect, report and remit to the Operating Carrier any non-interlineable Ticket Taxes
         levied in connection with sales of the Codeshare Flights.

         (b)  The Ticketing Carrier shall collect, report and credit to the account of  the Operating Carrier with ACH any
         interlineable Ticket Taxes levied in connection with the sales of the Codeshare Flights.  The Operating Carrier shall remit

         (c)  The Operating Carrier may bill the Ticketing Carrier for any Ticket Taxes due or payable on or measured by passenger
         enplanement and payable or remittable by the Operating Carrier which should have been collected at the time of ticket sale
         or travel document issue.

(3) If either party receives notice from any taxing authority with respect to any assessment or potential assessment or imposition of
any Tax (collectively, an "Assessment"), that the other party may be responsible for paying, directly or indirectly, the party so
notified shall inform the other party in writing within ten (10) days of receipt of such notice.  If the party receiving such notice
from a taxing authority is or will be required to pay any Assessment for which the other party is ultimately responsible, it shall be
entitled to be indemnified against such Assessment in accordance with Section 25(4).

(4)  Each party further agrees to indemnify, defend and hold harmless the other from and against any and all Taxes, or Assessments,
as the case may be, levied upon or advanced by the indemnified party, but that ultimately the indemnifying party would be responsible
for paying, which resulted from any transaction or activity contemplated by this Agreement.
