Frontier Airlines offering low fares, direct flights from Buffalo

Frontier Airlines will begin service out of Ontario International Airport officials announced Tuesday morning

Denver-based Frontier Airlines today announced a major expansion of its network, including the addition of daily nonstop service from General Mitchell International Airport in Milwaukee to Miami and to Tampa, Florida, beginning this fall.

The airport has added services from three new airlines and nonstop flights to nine destinations in the past 12 months, according to airport officials.

United Airlines president Scott Kirby offered harsh criticism of Frontier Airlines' day-old plans to launch 21 new routes from its Denver base by the spring of 2018.

To celebrate its expansion, Frontier is offering for a limited time fares from $39. "We project this will save our customers over a billion dollars annually on their flights". For example, Frontier's new routes will make it the airline with the second most destinations from cities like Orlando, behind Southwest.

Non-stop flights to Buffalo, Cancun, Cedar Rapids, Grand Rapids, Knoxville and Oklahoma City are now on sale and nonstop trips to San Antonio and Tulsa will be available for spring travel.

Frontier discontinued service in Tulsa in April 2010 when it offered flights only to Denver, said Stephanie Chester, community relations manager for the Tulsa Airports Improvement Trust.

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.

The flight schedule and the start of ticket sales will be announced at a later date.

The airline's return to OKC is part of its expansion into 21 cities and 85 new routes across the US, according to Sean Morahan, director-stations at Frontier. "When an airline like Frontier decides to expand its presence to the point where we now have 15 routes from Miami here, that says a lot about the ability to draw quality airlines to our airport".
