On Tuesday, Frontier Airlines announced the addition of 85 new routes and 21 new cities to its network.
By next summer, the airline expects to double the number of daily non-stop flights it operates to 314.
To accompany its new expansion plans, the Denver-based ultra-low-cost carrier is offering tickets for as low as $US39.
“We are proud to announce the nationwide expansion of our unique brand of Low Fares Done Right which will empower millions more people to afford to fly,” Frontier Airlines president and CEO, Barry Biffle, said in a statement.
“We project this will save our customers over $US1 billion annually on their flights. These new flights will allow us to serve even more of America and make flying a truly affordable option.”
Frontier’s massive expansion represents a major assault on established industry powers like Southwest, United, American. The bulk of Frontier’s expansion will take place in Denver, Miami, and Orlando where its rivals all have significant investment and market share.
According to Frontier, its new routes will allow the airline to serve 90% of the US population.
The once bankrupt airline has flourished since adopting an ultra-low-cost business model a few years ago. Frontier, along with Florida-based Spirit, has spearheaded the growth of the ULCC in the US — forcing major legacy carriers to adapt with new products such as basic economy fares.
In march, the airline filed paper work for with the Securities and Exchange Commission for an impending IPO.
Frontier currently operates a fleet of 70 new Airbus A320-family narrow-body airliners that is expected to grow to more than 100 planes by 2020.
