In IRROPS, you are either stuck for days or wind up purchasing a ticket on a real carrier for a lot more real money.
I have never flown on Frontier (or Spirit or Allegiant), and I am not recommending that anyone do so. But it appears that there is now a relatively low-cost way of insuring against IRROPS on these carriers:

A Freebird rep has confirmed to me that if you have a covered flight from or to an airport with little or no other service, Freebird will rebook you to or from a nearby airport at your request (e.g., EWR instead of TTN).
