"It's no secret that we are busting at the seams right now with all the growth that we've seen from Frontier, from our other carriers here", said Patrick Heck, Chief Commercial Officer at Denver International Airport. It previously offered service in Oklahoma City, but the company left in 2015 in order to cut costs and refashion itself as a budget airline.
The Denver-based carrier announced the four weekly nonstop flights on Tuesday. Seats for the introductory fares are limited and valid for travel between October 5 and March 8, Frontier said.
"We project this will save our customers over $1 billion annually on their flights".
"By taking advantage of our natural share of connecting passengers, we can offer our low fares to even more of America, '" Biffle said.
Adding to its current destination count of 50-cities from DIA, Frontier's new routes will all be offered by the summer of 2018.
Frontier operates a fleet of 69 Airbus A320-family aircraft, with a further 73 on order.
Frontier has become increasingly popular in recent years by offering no-frills flights for as low as $59.
"With today's return announcement, it's a sign Frontier once again recognizes the value of the Palm Springs resort destination to their Denver market", said City Manager David H. Ready.
The training location will serve the airline attendants who are based out of the Orlando, Philadelphia and Chicago airports.
Over the last decade, the carrier has been transformed from a bankrupt legacy carrier into a rapidly expanding, ultra-low cost airline under new management.
"We're going to have something set up now where over 90 percent of America will be within one hour of a Frontier flight to anywhere else in the USA", said Howard Diamond, general counsel for Frontier Airlines, at a press conference held at TIA.
