Frontier is increasing the number of miles for an award ticket and imposing ticketing fees, citing rising fuel cost even as oil has fallen substantially from its highs. Cutting frequent flyer program benefits usually doesn’t happen while a carrier is in bankruptcy. In general we’ve seen the opposite — print funny money (miles are a currency) while in bankruptcy and reduce the value of those miles once exited from Chapter 11. So this turns the usual expected practice on its head.

The upshot of the changes is that Frontier

will charge customers $25 per award ticket, and $75 per award ticket for flights booked within 14 days of travel.

Redeemable tickets will jump from 15,000 miles to 20,000 for a domestic round trip ticket.
