Frontier announced Friday that their decision to stop all services to Aspen came as a result of suspending all operations on the Q400, which is the turboprop that Frontier uses for the Aspen–Denver flight, according to The Aspen Times.

United Express and American Eagle will be the only two airlines that will continue to service flights to Aspen during the summer months.

Anyone who booked a flight on the single daily connection between Aspen and Denver offered on Frontier after April 15 will be accommodated on United, Bill Tomcich, president of reservations agency Stay Aspen Snowmass, told the newspaper.

This comes a day after Frontier announced they were adding five more nonstop routes from Denver.

Following are schedules for the new Denver nonstop routes:

• Denver-Bloomington, Ill. (Begins May 18)
• Denver-Cedar Rapids, Iowa (Begins May 17)
• Denver-Bellingham, Wash. (Begins May 24 to Sept. 16)
• Denver-Great Falls, Mont. (Begins May 14 to Sept. 30)
• Denver-Harrisburg, Pa. (Begins May 22 to Sept. 9)
