The service cutbacks from Philadelphia do seem extensive and a bit strange. I'm not really sure what's happening, and I don't see any media coverage of this development (of course, few people seem to really care what Frontier does). I thought the reduction of service to Denver might be seasonal, but I don't see it back for next winter. I also don't see Vegas back. It is possible Frontier is "giving up" on PHL, or perhaps they're just being their usual not-very-competent selves. I do feel the pain for anyone in Philly who bought a travel pass or a status match upgrade.

EDIT: I do see the PHL - DFW flight still on the schedule. Is that the only thing they're operating out of Philly west of the Mississippi? I recall reading that they were going to offer NEW flights out of PHL next winter. Like I thought they were adding service to Houston. I don't actually see that flight on the schedule, though.
