American Airlines US flights hit by computer glitch

[mhm]

American Airlines had to ground all its flights across the US for several hours on Tuesday due to a fault with its computerised reservation system.

The carrier halted all departures from about 13:30 ET (18:30 GMT), saying that it was working ""to resolve this issue as quickly as we can".

American fixed the problem three hours later, but warned that it expected to see delays and cancelations continue for the remainder of the day.
