Frontier Airlines is ceasing direct flights from Birmingham to Philadelphia three months after launching the service.

The final flight will be on July 4, said Toni Herrera-Bast, marketing manager for Birmingham Airport Authority.

"Frontier's service to Orlando and Denver will continue and we are working with them as well as our other airline partners to pursue other route opportunities to meet the need of our traveling community," she said.

Herrera-Bast said American Airlines will continue service to Philadelphia.

Frontier Airlines announced in February that it would start offering direct service from Birmingham in April. Daily service isn't offered.

Flights to and from Denver are offered on Sunday, Tuesday and Thursday. Flights to and from Orlando will be offered on Monday and Friday.

When emailed for comment, Frontier Airlines didn't explain why the service was being canceled.

Headquartered in Denver, Frontier Airlines offers ultra low-cost fares starting as low as $39 one way. It's motto is 'Low Fares Done Right.' There are fees, however, for both carry-on and checked bags.

At a February press conference, William Evans, senior manager of sales and distribution for Frontier Airlines, said the airline was starting with service to Orlando and Philadelphia because those are Frontier's fastest growing cities and Denver is Frontier's hub.
