Southwest Airlines resumed departures Tuesday afternoon after grounding all flights in the US because of a “technical glitch.”

“We should hopefully be resuming our operation as soon as possible,” Southwest said on Twitter.

 

A similar situation during the Christmas Holiday Season caused the cancelation of more than 17,000 flights.

“I’ve been sitting on a plane from Las Vegas to San Diego for 2 hours waiting for a ‘weather report,’” one person wrote on Twitter. “This 45 minute flight will now take 4 hours. What a complete joke and waste of time.”

“Sitting on the tarmac at Midway due to a computer problem causing a @SouthwestAir nationwide ground stop,” another wrote. “Airlines require systems that have 99.999% uptime. Time to install some new IT leadership that takes availability culture seriously.”
