MINNEAPOLIS (WCCO) — Sun Country Airlines has canceled some domestic flights at MSP Airport Monday morning due to a system outage.

“Sun Country Airlines has received reports of a temporary third-party network system outage affecting all Sun Country flights, as well as the flights of many other airlines worldwide,” the airline said in a statement. “As a result, this morning, domestic flights scheduled before 8 a.m. CT were canceled and passengers were issued full refunds and waived change fees.”

Sun Country said it was working with the Federal Aviation Administration to manually clear flights for takeoff.

“We appreciate the patience of our guests as we work to get them safely on their way as quickly as possible,” the airline said.

In a mid-morning update, Sun Country said it has been able to successfully operate all but one flight after 8 a.m. — the cancellation was not related to a system outage.

Here’s a statement released by the airline:

“This morning, December 27, 2021, Sun Country Airlines was made aware of a temporary third-party system outage affecting all Sun Country flights. Currently, our Operations team is continuing to execute our manual process and working closely with the FAA to clear flights for takeoff. As we continue to work through the disruption, we anticipate delays throughout our system however, we feel confident we’ll be able to successfully operate today’s remaining flights. Our goal is to ensure our passengers can continue their travel as planned. We will continue to provide more information as it becomes available. We appreciate the patience of our guests as we work to get them safely on their way as quickly as possible.”

Over the holiday weekend, hundreds of flights nationwide — including dozens at MSP — were canceled or delayed due to weather and staffing shortages.
