It'd seem odd to cut off Dulles so soon, unless it has been really underperforming. Also, it just applied for IAD-NAS and IAD-CUN.

I've wondered if the Dulles expansion was there to justify the 3x daily on DCA-DEN so that DC pax would know and book use F9 as a ULCC. But to DC pax, this was likely as exciting as a Dollar Tree opening up in Tysons Corner Mall. Has Frontier caught on with the DC region?

I'm still puzzled with TTN-CLE disappearing given the focuses on both ends. Maybe if Frontier didn't alter the schedule so much by removing the Sunday flight and then operating it as a 6:30am flight on random days, it'd do better.

It'd be nice if it got it's original modest schedule back of twice weekly on Sunday (afternoon) and Thursday. I know it's slim, but given that ACY does well with Spirit, and TTN and ILG might be dedicated for Florida and sun destinations and a few major markets like DTW MDW and ATL, I'd hope maybe CLE, PIT and DEN could open from ACY.
