After a three-year hiatus, Frontier Airlines is returning to Spokane.

The Denver-based carrier will resume flights to and from Denver on April 30. Direct flights will run four times a week – Monday, Wednesday, Friday and Saturday, said Richard Oliver, a company spokesman.

The budget airline pulled out of Spokane and about a dozen other cities in early 2015, shifting resources to larger cities in the eastern U.S. and particularly focusing on Atlanta.

But in recent months, Frontier has added about 100 new routes connecting dozens more cities nationwide, including Albuquerque, Boise, Calgary and Reno. The airline now serves 84 cities, primarily in the U.S but also in Mexico, Canada, Puerto Rico and the Dominican Republic.

Departing flights will leave Spokane International Airport at 7:20 p.m. and arrive at Denver International Airport at 10:35 p.m. Return flights will depart Denver at 4:55 p.m. and arrive in Spokane at 6:19 p.m.

The Spokane flights will leave from Gate A14 and use the ticket counter adjacent to Delta’s, according to Todd Woodard, the local airport’s spokesman.

Frontier’s website indicates the price of flights will be between $39 and $120 each way, but that price can change if the purchaser is a member of a special program called the Discount Den.
