American Airlines requested a nationwide ground stop, which was later canceled, on the morning of Christmas Eve due to technical problems.

American Airlines grounded all of its flights across the US for an hour on Tuesday, saying it was experiencing technical issues as airlines gear up for the Christmas travel rush. The Federal Aviation Administration said in an advisory statement early on Tuesday morning that the airline's flights across the US were grounded.

American Airlines said on Tuesday its flights had resumed after a technical glitch forced the carrier to issue an hour-long ground stop, disrupting travel for thousands on Christmas Eve, one of the busiest periods of the year.
