NEW YORK (AP) — Southwest Airlines canceled hundreds of flights over the weekend, blaming the woes on air traffic control issues and weather.
The airline canceled more than 1,000 flights, or 28% of its schedule as of 5 p.m. ET Sunday, according to flight tracker FlightAware.
The cancellations mark the highest rate by far of the major U.S. airlines.
Next in line are Allegiant and Spirit, both of which had canceled 5% and 4% of its flights respectively, according to the flight tracker.
American Airlines canceled 2% of its flights.
Southwest said in a statement that it is working diligently to reset operations and is allowing customers to rebook themselves on their website.
