NEW YORK — Thousands of Delta Airlines passengers were stranded for hours Monday after a global computer system outage caused large-scale cancellations.

Delays and cancellations continued as of 1:15 p.m., according to Delta. The airline had 6,000 flights scheduled for Monday and canceled more than 450 of them because of the power issues. Delta is working to correct the issue as quickly as possible.

"It's an all hands on deck effort," said Delta CEO Ed Bastian.

Experts believe the outages will cost Delta tens of millions of dollars and take several days to recover from.

"You have airplanes and crews out of place. You've got passengers all over," said airline consultant Mike Boyd. "This is something you can not completely prepare for."

Original post: Delta Airlines passengers are experiencing delays worldwide Monday morning due to a system-wide computer failure.

A power outage initially occurred in Atlanta around 2:30 a.m., impacting the airline's computer systems and operations worldwide.

"Large-scale" cancelations are expected on Monday.

"We are aware that flight status systems, including airport screens, are incorrectly showing flights on time," an online news release stated.

Delta is urging all passengers to check their flight status before getting to the airport.

All flights that are "en route are operating normally," but flights awaiting departure are delayed.

Delta issued a waiver for customers traveling on Monday, saying they now have until Friday to fly. Those interested are encouraged to visit the airline's website for details.

Passengers who booked a flight on Monday but did not have a canceled flight can make a one-time change to their tickets without normal fees.

Fights awaiting departure were grounded early Monday morning, according to the Delta Twitter account.

Frustrated customers posted about the delays throughout the morning on social media, including a flyer at LaGuardia Airport who tweeted video of a fire alarm going off at the airport's Delta terminal.

"It's just comedy at this point," Andrew Stallings said of the ordeal, adding that he was sure Delta officials are doing all they can to remedy the situation.

Employees at LaGuardia told Stallings the system was being tested.

The cause of the outage is currently unknown.

The Delta problems on Monday came less than three weeks after Southwest Airlines canceled more than 1,000 flights following a system outage.
