Denver based Frontier Airlines says it is adding blackout dates to its award redemption tickets but concurrently increasing redemption seat availability options by 30%. For example, traveling the day before or the day after Christmas are considered blackout dates and you couldn't use miles for to redeem for such an itinerary (Christmas day itself is OK though). "EarlyReturns will be better equipped to guide you towards dates that have seats available. Adding this flexibility to the program will allow you to use your miles for more flights" says Frontier in a written email to its Early Returns members.Also, Rocky Mountain news reports Frontier will be swapping out seats, for a thinner and lighter version, ultimately adding 4 additional seats on most planes and a reduction of seat pitch of 1-2 inches, though reportably no loss to leg space.
Frontier Airlines currently operates flights from San Francisco, San Jose and Sacramento, and is one of only a few U.S based airlines still offering round trip Domestic U.S & Canada award redemption's starting at only 15,000 miles.
