DENVER — More than 500 flights were canceled or delayed at Colorado's biggest airport on Monday.
Overnight Sunday into Monday, Denver International Airport received half an inch of snow. As of 10 p.m. Monday, there were 561 delays and 75 cancellations at DIA. Southwest Airlines had the most delays, followed by United Airlines and SkyWest Airlines.
On Sunday, there were more than 650 delayed flights and 63 canceled flights at DIA, according to FlightAware, as the airport dealt with an issue with its baggage system and airlines grounded Boeing 737 Max 9 planes after an inflight blowout.
DIA confirmed a mechanical issue took place Sunday morning with its baggage system. They said that issue was resolved and employees were working to get backlogged bags through the system and onto appropriate planes. Southwest said that trouble with a mechanical baggage belt impacted multiple airlines at DIA. A spokesperson for Southwest said that issue was fixed around 9 a.m. Sunday.
"The situation is improving, and we are working hard to get bags loaded as quickly as possible," Southwest said on social media around 10:20 a.m. Sunday.
Bobbi Mason arrived at the airport around 3:30 p.m. Sunday for a flight home to Houston. At 4:10 p.m., she was still standing outside, in line for Southwest's baggage check-in. Her flight was set to depart at 5:30.
While in line, she worked on a plan to get back to Houston, with kids who had to get back to school. She stayed in line for another hour before she and her family went to a hotel. They're booked for an early flight Monday morning.
Also Sunday, Alaska Airlines and United grounded all of their Boeing 737 Max 9 jetliners again while they waited to be told how to inspect the planes to prevent another inflight blowout like the one that damaged an Alaska jet Friday. Alaska and United are the only U.S. airlines that fly the Max 9.
United said it has 79 Boeing 737 Max 9 aircraft, and that it was working to accommodate customers who were impacted.
"We are working with customers to reaccommodate them on other flights and in some cases have been able to avoid cancellations by switching to other aircraft types," the airline said in a statement Sunday afternoon.
