Federal statistics show that in a five-year span ending with 2016, United Airlines bumped more than 42,500 passengers (who were holding confirmed reservations) involuntarily from flights because the company had overbooked the flight.
That equals about 1.06 involuntary bumps for every 10,000 passengers United served during those years, which was a higher rate than only two other major airlines in the country during those years.
EspressJet Airlines, which operates flights under the United Express, American Eagle and Delta Connection names, had the highest rate of about 2.09 involuntary bumps per 10,000 passengers, followed by SkyWest Airlines, which had a rate of about 2.03.
United was trailed fairly closely by Southwest (1.01) and Frontier (0.97).
Still, the data show that United’s track record improved considerably over those years.
In 2012, United’s rate of involuntary bumps was 1.83. But last year it was 0.43, which was better than the average of 0.62 among major airlines.
United’s improving numbers are in line with the broader trend within the industry in recent years, as major airlines, collectively, have lowered the rate at which passengers are involuntarily bumped.
Airlines are allowed to sell more tickets than there are seats on the plane, and they routinely overbook flights because some people do not show up.
If that approach doesn’t work, airlines can demand that passengers give up their seats.
Airlines are required by federal rules to give all passengers who are bumped involuntarily a written statement describing their rights and explaining how the carrier decides which passengers get bumped. Such passengers also frequently are entitled to compensation, depending on how much they paid for their ticket and how long they are delayed.
United has also bumped passengers voluntarily at a relatively high rate in recent years.
Three other airlines had higher rates: ExpressJet, at 17.3 voluntary bumps per 10,000 passengers; SkyWest, at 15.7; and Delta, at 10.1.
The data come from Air Travel Consumer reports published by the U.S. Department of Transportation’s Office of Aviation Enforcement and Proceedings.
Officials from United did not respond to a request for comment Monday afternoon.
