Holiday Travel in full swing at Miami airport, Despite American Airlines Delays

American Airlines resumed flights Tuesday after a technical issue forced the world's largest carrier to ground all its US flights for an hour during the busy year-end travel period, officials said.

" American Airlines reported a technical issue on the morning of 24th December and requested a nationwide ground stop.

The ground stop has now been lifted," Bridgett Frey, Assistant Administrator for communications at the Federal Aviation Administration, said in a statement.

The flight halt between 1150 GMT and 1250 GMT came on Christmas Eve, a day of exceedingly heavy air travel in the United States and elsewhere.
