Unexpected storms diverted 100 American Airlines flights and sparked hundreds of cancellations

More than 320 American Airlines flights had been cancelled by midafternoon Thursday, or 10% of its schedule, according to flight tracking site FlightAware. A total of about 700 US flights had been cancelled by Thursday afternoon. More than 4,500 flights were delayed by Thursday afternoon.

On Wednesday, American cancelled nearly 370 flights. A total of more than 1,200 US flights were cancelled on Wednesday, FlightAware data shows.

DFW airport is American Airlines' largest hub.

Southwest Airlines, headquartered in Dallas, logged about 250 cancellations on Wednesday, according to FlightAware. Southwest cancelled about 100 flights on Thursday.

Caught off guard by second line of storms

According to American's Chief Operating Officer David Seymour, the airline prepared for thunderstorms in the forecast south of the airport on Wednesday afternoon. But another wave came by surprise.

"Those storms then regenerated and created an entirely new, and unanticipated, line of storms north of the airport. This unexpected storm activity prevented all arrivals into DFW for a three-hour period," Seymour said in a memo to staff shared with CNN Travel.

One hundred AA flights were diverted, and the airline proactively cancelled all remaining flights into and out of DFW on Wednesday.

"DFW airport had gone 67 days without seeing measurable rain, the second-longest streak on record -- weather like this can wreak havoc on our operation. This was the worst storm we've seen at DFW this summer, and to make matters worse, there was no indication it was on its way," Seymour said.

He thanked American Airlines' staff for their efforts in recovering from the weather disruption and noted that cancellations are "hugely impactful to our customers."

"Canceling flights is a last resort," Seymour said in the memo to staff. "But doing so in advance -- even with a small window -- gives customers the best chance to adjust their plans and avoid last-minute issues at the airport."

DFW Airport said Thursday that it has resumed normal operations.

A summer of flight headaches

Summer's severe weather has been compounding other operational challenges, including staffing at airlines and airports.

Transportation Secretary Pete Buttigieg has been working to address air travel disruptions as the demand shattered by the pandemic has come roaring back.

This past weekend was hit with delays and cancellations, with Friday the worst day for cancellations since mid-June.
