SkyWest Airlines’ Essential Air Service Proposal for West Yellowstone, MT

Dear Mr. DeVany:

Attached is SkyWest Airlines’ proposal for service at West Yellowstone, Montana. Our 

proposal is to provide direct service from West Yellowstone to Salt Lake City 

International Airport.

SkyWest welcomes the opportunity to continue serving the West Yellowstone 

community. Our combination of safe and reliable aircraft, well-timed schedules, and 

access to one of the world’s largest airline networks provides passengers quality air 

service and will also help drive economic growth in the region.

Delta Air Lines’ Network

One of the most beneficial aspects of SkyWest’s proposal is that it provides West 

Yellowstone passengers with continued access to Delta Air Lines’ global network. Delta 

is a founding member of the SkyTeam alliance, providing seamless connections aboard 

5,400 daily flights and unparalleled access to nearly all parts of the globe.

Frequency and Schedule

As directed by the RFP, we will offer a minimum of 14 round-trip flights per week. All 

flights have been timed to ensure they offer passengers valuable flight schedules that 

arrive and depart on bank. This means that they have been optimized for maximum 

connection opportunities in Salt Lake City, making the service convenient for both 

business and leisure travelers.

With nearly 300 daily departures, Delta operates more service from Salt Lake City 

International Airport than any other airline and offers hundreds of connections to 

destinations around the globe. In addition to being a major hub, Salt Lake is also among 

the top destinations for those living in the West Yellowstone catchment area.
Superior Aircraft 

Service will be provided utilizing the Embraer Brasilia 120 (EMB 120) 30-seat turboprop 

aircraft. SkyWest is the largest domestic operator of this reliable and proven aircraft type, 

and the aircraft is already available for service on the route. 

All SkyWest EMB 120 aircraft are equipped with a lavatory and each flight is serviced 

by one of our highly-trained flight attendants, further adding to the comfort and 

convenience of our passengers’ flying experience. Additional details and specifications 

can be found in the EMB fact sheet attached to this document. 

Contract Duration

We propose a one-year contract to provide EMB service in West Yellowstone. This 

would cover the 2012 summer season only. 

The West Yellowstone airport is currently completing the steps necessary to secure 

regulatory approval for scheduled, commercial jet service – a long-term goal for the 

market. Given the uncertainty in the timing of the approval, we propose operating the 

EMB 120 through summer 2012 only. If jet service is approved, we would consider 

bidding for future service using a Bombardier Canadair Regional Jet 200 (CRJ200).

Summary

SkyWest believes this proposal provides the best overall option for air service in the West 

Yellowstone community. Given the connectivity at Salt Lake City, the well-timed 

schedule, and reliable equipment, we expect to see continued growth in the number of

passengers utilizing the service. We will also continue working with community and 

airport partners to market the service. 

SkyWest is excited about the possible opportunity to continue providing reliable air 

service to West Yellowstone, Montana. 

Thank you for your consideration.

Sincerely,

Michael Thompson 

Vice President – Market Development
