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.

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

American Airlines flights across the nation were disrupted Tuesday by a reported technical issue, but the hour-long ground stop has been lifted and flights have resumed at airports, including San Diego International Airport.
