FWIW, I see United's got someone manning Twitter watching for complaints:

Understanding the Summer Air Travel Mess

Going into the Fourth of July weekend, with nearly 13 million people expected to fly on U.S. carriers, we look at the numbers behind the delays and cancellations and see what lessons can be learned.

More people flew out of airports in the United States on Sunday — 2.46 million according to the Transportation Security Administration — than on any other day so far this year. The Fourth of July holiday is expected to be even busier, with Hopper, a travel booking app, predicting that nearly 13 million passengers will fly to, from and within the United States this weekend.

The question for many travelers is whether they can trust airlines to get them where they want to go on time.

You could not blame them for assuming the answer is no. On June 17, the Friday before the Monday Juneteenth holiday, nearly a third of flights arrived late, according to FlightAware, a flight tracking company. Between last Saturday and Monday ahead of the Fourth of July weekend, U.S. carriers already canceled nearly 2,500 flights. In a June 16 meeting, Pete Buttigieg, the transportation secretary, told airlines that he’d be closely monitoring their performance. The very next day, his own flight from Washington to New York was canceled.

In a letter on Tuesday, Senator Bernie Sanders urged Mr. Buttigieg to begin fining airlines for particularly egregious cancellations and delays. Among other proposals, he suggested that airlines should pay $55,000 per passenger for any canceled flight that it was clear in advance they could not staff.

Before postponing any upcoming trip, though, it’s worth taking a close look at cancellation and delay data for insights into how travel has, and has not, changed this year [....]

Percentage of cancellations so far this year vs. a comparable time in 2019: 2.8 percent vs. 2.1 percent.

Lesson: The idea that air travel was so much better before the pandemic may be clouded by nostalgia for Before Times.

video looks like I remember it the last time I was there, I guess there's always something like bomb threat going on at JFK,
