ATLANTA (AP) — Hundreds of flights worldwide were cancelled by midday Sunday, adding to the mounting number of scrubbed flights during the busy Memorial Day holiday weekend. Just over 1,000 flights had been canceled as of 11 a.m. EDT Saturday, according to tracking website FlightAware. That follows more than 2,300 cancellations Friday and another 1,500 on Saturday. More than 250 of Sunday’s cancellations involved aircraft scheduled to fly to or from U.S. cities. Delta Air Lines cancelled the most flights among major U.S. airlines. Delta said Saturday’s cancellations were because of bad weather and “air traffic control actions.”
