American Airlines has canceled more than 1,000 flights since Friday, disruptions it blamed on staffing problems and high winds at its busiest hub.
On Saturday, American canceled nearly 460 flights, or 17% of its mainline schedule, according to flight-tracking site FlightAware. Dallas-based Southwest Airlines cut 86 flights, or 2% of its Saturday operation.
American canceled another 285 flights, or 10% of its schedule planned for Sunday, on top of 340 cancellations on Friday.
American’s COO David Seymour said in a staff note on Saturday that the problems started with high wind gusts on Thursday that cut capacity at its Dallas/Fort Worth International Airport hub and that crew members ended up out of position for their next flights.
Pilot and flight attendant availability were listed as reasons for most of the cancellations on Saturday and Sunday, according to internal tallies, which were seen by CNBC.
