Just to clarify that - I could easily imagine Frontier going 2 x daily on some days on certain routes - TTN-MDW/RDU on Fridays and Sundays, perhaps, and maybe ATL on Sundays.

But I wouldn't imagine it will happen until next spring, if at all, and I think it will be a while before they go even 1 x daily on most of the routes.

Equally, I think it is possible they may go daily ILG-DEN but again, not until next summer, and probably only for the summer.
