Airport terminals took on a more normal look Wednesday as U.S. airlines canceled far fewer flights and began the job of digging out from a blast of polar air.
By midafternoon, about 770 flights within the U.S. had been canceled, according to tracking service FlightAware.com. That's down from nearly 2,700 cancelations on Tuesday and 4,100 on Monday.
The largest numbers of U.S. cancelations on Wednesday — more than 100 each — were on ExpressJet and Chautauqua, according to FlightAware. Those carriers operate smaller regional flights for the big airlines and usually are the first to have flights scrubbed when there's bad weather. Delta, United, American and Southwest had canceled 1 percent or fewer of their flights.
