# January 24, 2012 Dennis J. DeVany Office of Aviation Analysis US Department of Transportation 400 Seventh Street, S.W. Washington , D.C . 20590 SkyWest Airlines ’ Essential Air Servi ce 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 . O ur combination of safe and reliable aircraft, well - timed schedules, and access to one of the world’s largest airline network s 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 provide s West Yellowstone passengers with continu ed access to Delta Air Lines’ global network . Delta is a founding member of the SkyTeam alliance , providing seamless c onnections 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 destination s 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 reli able 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 attendant s , 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 serv ice 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 beli eves this proposal provides the best overall option fo r air service in the West Yellowstone communit y . 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 yo ur consideration. Sincerely, Michael Thompson Vice President – Market Development SkyWest Airlines
