This document contains the response of Great Lakes Aviation, Ltd. to Order Requesting 

Proposals 2011-8-18.

Great Lakes' proposal contemplates non-stop, conveniently timed connecting services to our 

code share partners (United Airlines and Frontier Airlines) at our Denver Hub. Our code share 

agreements will give the Pueblo community the greatest competitive oppourtunity available in 

the Rocky Mountain Region. In addition, Great Lakes maintains interline ticketing and baggage 

agreements with the majority of the other carriers serving Denver, including interline electronic 

ticketing (IET) agreements with American Airlines, Continental Airlines, Frontier Airlines, United 

Airlines and U.S. Airways. All of which will offer passengers maxium access to the domestic 

and international air transportation system.

The proposed service is submitted without any upline scheduling restrictions and contemplates 

the use of 19 seat Beechcraft 1900D airliner equipment. 

Great Lakes Aviation, Ltd. is pleased to submit this proposal to provide essential air 

transportation. The company has more than 20 years of history of providing reliable Essential 

Air Service. This proposed service is being offered with local service marketed and priced 

utilizing the Great Lakes (ZK) Reservations system which includes customer ticket purchasing 

capability on both Great Lakes web site and on all major Web Booking Engines (Orbitz, 

Travelocity, Expedia, etc.)
