More than 200 Southwest Airlines flights were canceled or delayed at Dallas Love Field on Sunday, data shows.
The website FlightAware, which tracks delays and cancelations nationwide, showed 139 Southwest flights were canceled and 100 were delayed at the Dallas airport as of 11 p.m. Sunday.
The number of cancellations amounts to more than one-third of all Southwest flights out of Love Field. No other airlines canceled flights out of the airport Sunday. There were just eight other delays on three different carriers.
The Southwest delays and cancelations at Love Field come a day after the airline canceled 70 flights and delayed 138.
The problems at Love Field were part of a larger issue nationwide for Southwest Airlines, which canceled more than 1,800 flights across the country this weekend.
Southwest Airlines said Saturday the canceled and delayed flights were caused by air traffic control issues and bad weather in Florida. The airline urged customers to rebook and check their flight status on Southwest.com.
"We experienced weather challenges in our Florida airports at the beginning of the weekend, challenges that were compounded by unexpected air traffic control issues in the same region, triggering delays and prompting significant cancellations for us beginning Friday evening," a Southwest Airlines spokesperson said in a statement. "We’ve continued diligent work throughout the weekend to reset our operation with a focus on getting aircraft and crews repositioned to take care of our customers."
