More than 1,400 US flights were canceled on Friday

More than 1,400 flights scheduled to take place Friday into, into or leave the United States have been canceled, according to flight tracking website FlightAware, as airlines continue to struggle with on-time departures this summer.

Along with 1,482 cancellations, airlines had more than 7,000 delays on Friday within, in or out of the U.S.

Among US airlines, American Airlines had the most cancellations with 263, while Southwest was second with 193 cancellations.

Airlines have struggled this summer with persistent cancellations and delays that have frustrated customers and lawmakers.

Earlier this week, Democrats introduced legislation to provide cash refunds for flight cancellations amid the disruptions.

The measure would require airlines to give customers cash refunds if their flights were canceled within 48 hours of their scheduled departure time.

“Enough is enough: Travelers are tired of wasting their valuable time fighting airlines to receive their legally mandated cash refunds,” Sen. Ed Markey (D-Mass.) said in a statement. “And they’re tired of booking flights months in advance, only to face a health scare that forces them to choose between canceling a non-refundable flight or traveling and risking the health of their fellow passengers.”

The flight cancellations and delays come as the airline industry has seen a decline from earlier in the pandemic, with people traveling in greater numbers again as pandemic restrictions and fears ease in the US
