Thousands of flights have been delayed in the United States after Southwest Airlines was forced to temporarily ground all flights because of a "technical glitch".
The airline said it would work to accommodate passengers disrupted by the one-hour nationwide stoppage.
Flight Aware says over 5,400 flights were delayed into our out of the US on Tuesday. More than 100 were cancelled.
It's the latest setback for the budget airline.
"This morning Southwest Airlines experienced a technical issue with one of their internal systems," the FAA said.
It added that all departures had been paused at the airline's request while the Dallas-based carrier addressed the issue.
