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 with quality air service and access to one of the world’s largest airline 

networks – crucial elements to continue driving economic growth in the region. Our safe, 

reliable aircraft and well-timed schedules will help ensure the best possible travel 

experience for passengers. 

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 arrive and depart on bank, meaning they have been optimized 

for maximum connection opportunities in Salt Lake City. This excellent connectivity 

makes the service convenient for both business and leisure travelers. 

With nearly 300 daily departures, Delta operates more flights 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 among the 

top destinations for those living in the West Yellowstone catchment area and provides 

great access for travelers in Salt Lake City to take advantage of everything West 

Yellowstone has to offer. 
Proven 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 professional 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. 

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 strong demand from 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, Mont. 

Thank you for your consideration. 

Sincerely, 

Michael Thompson
