United Airlines has followed American Airlines’ recent decision to offer special lower mile redemptions for short-haul flights. The two airlines have the two largest co-branded bank credit card programs in the USA. United announced this week it will now offer free roundtrip economy travel on flights under 750 miles for 15,000 miles, if the flights are booked on its Web site. Roundtrip domestic economy tickets generally require 25,000 redeemable miles, under United’s “Saver Award” rules. United is also offering free first-class and business-class short-haul tickets in exchange for 30,000 redeemable miles instead of the usual 40,000 miles. The updated program for United will go into effect September 1st and expires at year-end. American Airlines’ reduced award travel program, announced August 8th, will run from September 1st to February 28th.
