Good move by Frontier, and it suggests this is true:

"“This investment by Frontier indicates the airline’s commitment to Trenton-Mercer Airport,” Willmot said."

I'll be interested to see what the winter schedule looks like. I assume there will be some reduction on the non-Florida routes - it's hard to tell from the website - but I wonder if they'll add any more Florida , PBI, say, or JAX.

Or - be still my heart - NAS. :-)

Equally, PBI could go to ILG. That's the next puzzle - sorting out the balance between TTN and ILG. Good fun.
