Almost a quarter of a million flyers have joined the EarlyReturns program in the last year. To celebrate its first birthday, EarlyReturns will award members who fly four roundtrips to or from Portland or Seattle through June 15 an award ticket to anywhere Frontier flies.

The award ticket is in the form of a 15,000-mile bonus, which is enough for a free roundtrip ticket anywhere on Frontier’s route system. To enroll in the EarlyReturns program call (866) 263-2759 or visit the Frontier Airlines Web site at www.flyfrontier.com.
