Frontier Airlines is joining two other carriers in providing service from the Phoenix-Mesa Gateway Airport.
Monday’s announcement by the carrier followed about a year of negotiations.
The addition of the Denver-based carrier will triple the number of destinations reachable from the airport.
An exact flight schedule hasn’t been released.
Mesa Mayor Scott Smith says having Frontier as a third carrier legitimizes the airport.
Las Vegas-based Allegiant Air began serving the airport in 2008, and Florida-based Spirit Airlines since earlier this year.
