U.S. airlines have canceled more than 100,000 flights this year, with 30,000 cancellations just since Memorial Day weekend, according to data from flight tracking site FlightAware.

Mounting disruptions come as the number of air travelers reaches pandemic-era highs.

Flight cancellations in the United States are highest at New York-area airports, while three Florida airports make the top 10 for the most flight delays.

So who’s to blame for this messy summer travel season? Depends on whom you ask.

Short-staffed airlines say the federal government is also short-staffed at air traffic control facilities.

“From an industry perspective in the United States, New York, Newark and Florida really are air traffic control challenges,” United Airlines CEO Scott Kirby told CNN’s Richard Quest.

But the Federal Aviation Administration puts blame back on airline staffing issues as well as bad weather and heavy air traffic.

Transportation Secretary Pete Buttigieg recently told CNN that he’s seeing improvements, but he still expects airlines to do better.

“Look, we are counting on airlines to deliver for passengers and to be able to service the tickets that they sell,” Buttigieg said.

No matter how the summer air travel chaos is explained, it’s passengers who are caught in the middle.

A FlightAware analysis for CNN shows New York-area airports leading the nation for flight cancellations: Newark and LaGuardia are Nos. 1 and 2 among U.S. airports for flight cancellations.

Nearly 8% of flights leaving Newark have been canceled since May 28 and more than 7% of those leaving LaGuardia have been canceled. The other major New York airport, JFK, comes in at No. 9.

The data covers the period from May 28 through July 13.
