FORT WORTH, Texas — After more than 75 years of flying, the end is near for US Airways.

American Airlines plans to shut down the venerable carrier over a 90-day stretch that could begin as soon as July, which would mean a final departure around October.

American executives hope that a gradual fade-out will help them avoid the kind of technological glitches and massive flight delays that plagued United Airlines after it abruptly switched to Continental’s computer systems in 2012.

American and US Airways merged in late 2013 and decided to keep the American name. American expects to finish repainting all US Airways planes sometime next year.
