Southwest Airlines says that it has grounded flights nationwide due to “technical errors” as angry passengers blasted the company for delays on Tuesday — a repeat of the disastrous meltdown suffered by the carrier during the Christmas holiday.

“We have had to implement a ground stop as a result of intermittent issues that were experienced, and we should hopefully be resuming our operation as soon as possible,” a Southwest Airlines spokesperson tweeted on Tuesday in response to an angry customer who said they were “sitting in a plane waiting for computers to come back.”

“I apologize for any inconvenience this may cause, but we’ll be here for you if you need any assistance.”

“Once again sitting on a flight and being delayed. What is wrong with your leadership?? Isn’t time for a change and a new CEO,” one angry flier tweeted.

Another flier wrote: “Sitting on the tarmac because @SouthwestAir has fumbled operations yet again. So much for making it to work on time this morning.”

Another customer tweeted: “Any idea of when we can get off of flight 1924 in SJC? Can’t pull into a gate due to crashed computer system.”
