Delta is compensating customers who experienced delays after a computer outage Monday halted flights around the world.
The airline is offering $200 vouchers to passengers who experienced delays longer than three hours or had a flight cancelled, Delta announced in a release.
“We know that travelers value our commitment to excellent operational performance, and today we did not deliver on that commitment,” Gil West, Delta’s chief operating officer said in a statement. “We want our customers to know we are thoroughly investigating the matter and that we are truly sorry.”

Delta CEO Ed Bastian also apologized in a video posted on Twitter.
Hundreds of flights were cancelled and hundreds more were delayed earlier in Monday, leaving many passengers stranded after a loss of power in Atlanta that “affected Delta computer systems and operations worldwide.”
