Cancellations that were the result of a computer outage lingered into Tuesday.
Delta Airlines said 250 flight cancellations were reported in the morning hours, including several at Bradley International Airport in Windsor Locks.
Bradley said there were four cancellations and two delays on the departures side. For arrivals, there was on cancellation and two delays.
"We were able to bring our systems back online and resume flights within a few hours [Monday] but we are still operating in recovery mode," said Dave Holtz, senior vice president of operations and customer center. "We are sorry for what many of our customers have experienced over the past 24 hours, including those who remain at airports and continue waiting for their flights. We are doing everything we can to return our operation to normal reliability, but we do expect additional delays and cancellations."
The airline said the outage affected thousands of flights across the country. About 1,000 flights were canceled altogether while around 3,000 were delayed.
The outage happened at its headquarters in Atlanta.
It was repaired a few hours later; however, the damage to itineraries had been done.
As of Tuesday, the airline said it was still working to get delayed passengers wherever they needed to be.
It advised customers to check their flight status at delta.com or on the Fly Delta App. Customers can also re-book through Delta's website.
On Tuesday, Delta said it will provide $200 in travel vouchers to all customers who experienced a delay greater than three hours or a canceled flight as a result of the outage.
Customers who have not been contacted can reach out to Customer Care here to receive a voucher.
The airline said its travel waiver has been extended to customers traveling on Tuesday. It's offering compensation to customers significantly affected by the delays and cancellations.
Some customers were provided with hotel rooms and other accommodations if a cancellation required an overnight stay.
