Sure they can, but while there are a few rumours that some of that is on the cards nothing has been announced yet, which may affect whether they keep it as all A319 or assign the A320 to TTN.

And some of it is outside Frontiers control. It depends on what the airport wants to do how much spending the Freeholders are prepared to sanction.

There are also some questions as to whether all the Freeholders are in favour of too much more expansion, at least now, although I believe they have approved an application to the FAA for $2.5 million for improvements to taxiways.

As to the morning dead time, I agree, but one way to fix it may be to have some late night departures to nearer destinations with an early morning return to TTN.

The other unknown is the new owner, Indigo. They very much want more aircraft utilisation, so Frontier is bringing back red-eyes to some cities this summer. I don't know if that will eventually apply to TTN.
