The Biden administration is launching an investigation of competition in air travel

WASHINGTON — (AP) — The Biden administration said Thursday it is launching a broad investigation into the state of competition in air travel, including the effect of mergers and joint ventures between airlines.

The investigation is being handled by the Justice Department’s antitrust division and the Transportation Department.

The administration has successfully blocked three airline deals in the past four years, and President Joe Biden has criticized airlines for charging "junk fees."

However, the timing of Thursday's announcement — less than three months before Biden leaves office, and with the race to succeed him considered a toss-up — casts uncertainty over the fate of the investigation.

“Unfortunately, the timing of this 'broad inquiry', which was announced 12 days before a national election, suggests political motivations,” trade group Airlines for America said in a statement.

Four airlines dominate the U.S. airline industry — United, Delta, American and Southwest. They are the product of mergers that eliminated several major airlines.

The airline industry says that there is plenty of competition, however. The industry points to Transportation Department data that shows average U.S. airfares have generally declined for many years, although that has been partly offset by higher fees for baggage, premium seats and other items.

“Survey after survey shows that airline customer satisfaction is at an all-time,” Airlines for America said. “Air travel is at an all-time high.”

In the second quarter of this year, the average ticket was $382, according to the government figures. That is down from $404 in the same quarter of last year and $438 in the same period of 2019, before the coronavirus pandemic.

The departments said they would they also look into the way air travel is priced and sold, and airline frequent-flyer programs.

The agencies said they will take public comments until Dec. 23.
