DALLAS — Southwest Airlines flights appeared to be running closer to normal Tuesday after the airline canceled nearly 2,400 flights over the previous three days.

Southwest had canceled fewer than 100 flights, or 2% of its schedule, according to tracking service FlightAware. More than 400 other flights were running late.

Southwest maintains that bad weather and air traffic control issues in Florida on Friday triggered cascading failures in which planes and pilots were trapped out of position for their next flight. The crisis peaked Sunday, when Southwest canceled more than 1,100 flights, or 30% of its schedule.

“When you get behind, it just takes several days to catch up,” CEO Gary Kelly said Tuesday on CNBC.
