The American Airlines-US Airways merger closed on schedule Monday, as the carriers announced
it would two weeks ago. In a letter to frequent flyers of both airlines, the combined carrier assured travelers that the close will have no effect on existing reservations with either airline, nor on any frequent-flyer accounts. "We'll continue to function as two separate airlines for quite some time," reads the letter, "and very few changes will happen immediately." In early January, new benefits will be announced, such as the ability to earn and redeem miles on both carriers and to enjoy reciprocal lounge access.
