American Airlines and merger partner US Airways will award more frequent-flier miles to customers who buy first- and business-class tickets next year.
American dubbed the move — announced on Monday — as a "bonus mile promotion," though the offer will not require registration and will remain in effect for all of 2015. American says customers will automatically receive the extra miles on eligible flights.
American's offer comes as rivals United and Delta have switched to revenue-based frequent-flier systems. Under that set-up, those airlines will begin providing greater award mileage totals for more expensive airfares starting Jan. 1. American's change will help it narrow the gap between the miles it awards for its most expensive tickets and what Delta and United will start offering in 2015.
