I have had situations where the only nonstop flight for the day was cancelled (or moved from morning to evening), and I have successfully switched to a previous day. I've never tried to switch by more than one day but, as has been previously noted, this probably won't be allowed. But before you call or chat, have a good look at the schedule yourself to see what the possibilities are. Before you switch, you might even do better getting a refund and rebooking as Frontier's fares go down as often as they go up.

The saving grace of all this is that while Frontier is a PITA to deal with, their actual operation -- once it's finalized -- is surprisingly decent. While their airport and on-board experience is often subpar, the odds of your flight getting to its destination somewhat on-time are almost as good as flying on a "better" airline.
