Allegiant Air is making a bigger bet on the Philadelphia region this fall, announcing two new nonstop Florida routes that could mean cheaper travel options for thousands of local flyers. 

Starting Oct. 2, the budget carrier will launch nonstop service between Philadelphia International Airport and St. Pete-Clearwater International Airport.  

On the same day, travelers out of Trenton-Mercer Airport will gain a new nonstop option to Orlando-Sanford International Airport.  

Introductory one-way fares for both routes start at just $59, reports Emma Dooling and Breanne Williams for the Philadelphia Business Journal. 

The timing is no coincidence. The expansion follows the recent shutdown of Spirit Airlines‘ operations at PHL, leaving a gap in the region’s budget travel market that low-cost carriers are now racing to fill. 

“It is an important time for Allegiant to increase travel options in these markets,” said Drew Wells, Allegiant’s chief commercial officer.

“Our mission is to offer service where it is needed most, and these additions ensure that affordable fares can remain available to consumers despite industry changes.” 

The new Florida routes aren’t Allegiant’s first move into the area. The airline announced its Philadelphia and Trenton expansion plans in late 2025, and has since added flights from Philadelphia to Des Moines, Knoxville, and Grand Rapids, while growing Trenton service to Fort Lauderdale, Punta Gorda, and St. Pete-Clearwater. 

Beyond regional growth, Allegiant is also in the midst of a major corporate transformation, having acquired Sun Country Airlines in a deal valued at roughly $1.5 billion, a move that significantly broadens its national footprint.
