Details are now available on the previously-announced flight to Philadelphia (PHL). Looks like this may be more than just a summer-seasonal attempt at a money grab. Daily service starts March 13 on an Airbus A319. Flight times:

Philly 6:00am departure, arriving Charlotte at 7:45am

CLT departure at 8:25am, arriving PHL at 10:00am

Frontier’s other flight from Charlotte is to Trenton, NJ (Washington Dulles service ended last week). The Trenton flight now operates five days a week (all but Wednesdays and Saturdays), going to six days a week in April (not Saturdays), and daily in May.

And yes, it is good to more low-fare competition in Charlotte…
