Some flights from the Washington area’s three major airports remained affected Wednesday by the tornado outbreak in Texas, with a smattering of cancellations.

According to the Associated Press more than 500 flights were grounded Wednesday at Dallas-area airports.

Air traffic at Dallas/Fort Worth International Airport was shut down Tuesday afternoon following the outbreak of tornadoes in the metropolitan area, which the National Weather Service said may have totaled a dozen or more. Airport officials said dozens of airplanes suffered hail damage in the storm.

On Tuesday American Airlines announced via its Twitter account that it had canceled all of its DFW flights that evening. The airport remained open, and American officials said they were repositioning aircraft that had been diverted from Dallas. DFW is the airline’s largest hub.

American, which is based in Fort Worth, also warned that its call centers were experiencing heavy volumes and that callers should be prepared to for long waits.

Southwest Airlines, which is based in Dallas, also canceled several flights Tuesday to Dallas Love Field airport.

If your flight plans include Dallas, check with your airline to see how you are affected.
