Travelers are facing a second day of misery at airports across the country.

More than 1,300 U.S. flights were canceled as of 5 p.m. ET Friday with over 5,000 more posting delays, according to FlightAware, which tracks flights in real time.

The headaches come on the heels of one of the worst travel days yet as the peak summer vacation season heats up. More than1,750 U.S. flights were canceled Thursday.

Nationwide, American Airlines and Delta Air Lines have the most cancellations so far, with their schedules reduced by 8% and 7%, respectively, Friday. Those numbers do not include flights on their regional affiliates, which operate as American Eagle and Delta Connection.

"The vast majority of that is weather-related," said Curtis Blessing, spokesman for American Airlines. He noted that weather in the Miami area was also contributing to delays for the carrier on Friday morning.

Airlines kicked off the busy summer travel season by canceling about 2,800 flights in a five-day stretch around the Memorial Day holiday weekend, marking the start of what's likely to be a tough summer for the nation's air passengers.

Thursday and Friday's issues come in the wake of a virtual meeting between airline CEOs and Transportation Secretary Pete Buttigieg — a sign of the Biden administration's concern about the prospect of snarled airports and unhappy travelers this summer.
