DENVER -- Southwest Airlines said Monday morning that technology problems that spilled into a second day have been resolved.

The airline earlier said passengers should try to print their boarding passes before arriving at the airport. Intermittent technical issues on, the Southwest mobile app and the airline's phone centers could make doing so difficult.

But at 7 a.m., the airline released a statement that said the issues have been resolved.

Today we are expecting the technical systems that power our Customer Service to perform normally. Teams worked throughout the night in advance of our first departures to ensure the smoothest operation of our originating and later flights.

Out of the 3600 daily flights in our schedule on Sunday, the airline operated with 75 percent ontime performance. The technical issues did result in approximately 500 delayed flights Sunday. Employees worked around issues with primary systems and utilized back-up procedures to get our Customers and their checked luggage to their intended destinations.

We have some additional work to do to get bags delivered and some delayed or displaced Customers into open seats today. We have teams working as quickly as possible to accomplish that.

The flexibility we extended our traveling Customers on Sunday continues throughout Monday and that will allow those with travel plans scheduled for Sunday or Monday to change their plans at

It’s never too early to say thank you and to extend our apologies and we want to share those sentiments both with our hard-working Employees and our loyal and understanding Customers, whom we hope to welcome back for a better experience soon. We’ll continue to work individually with our affected Customers to make this right.

Those who get to the airport without boarding passes might have to be checked in manually, causing longer wait times. Southwest warned fliers to arrive at least two hours early, and advised customers to use kiosks to print boarding passes and bag tags.

Ticketing computers at Denver International Airport were up and running, and the check-in process was running smoothly.

"It was pretty easy," traveler Cecelia Jenkins said. "I know there were some things on the website telling us it was going to be delayed, but I just came in, I pre-checked, printed my ticket at home and dropped off my bag."

Southwest is typically a leader in on-time performance. The airline said no flights were canceled Sunday because of the problems. Customers are encouraged to use for updates.

Typically airlines that experience technology problems are able to correct it in a matter of an hour or two. That was the case when a glitch at United Airlines grounded 4,900 scheduled flights in July and again in September when computer problems affected American Airlines flights at some of its busiest hubs.

The airline has not said what caused the glitch.
