Major airlines and an industry trade association asked a federal appeals court to toss out a new Department of Transportation rule requiring earlier disclosure of add-on fees when booking flights.

The challengers — Airlines for America, along withv Alaska, American, Hawaiian, Delta, JetBlue and United Airlines — argue the DOT exceeded its legal authority when it published the rule in late April and that the rule is “arbitrary, capricious” and an “abuse of discretion.”

The petition for review was filed in the U.S. Fifth Circuit Court of Appeals late Friday.

The Biden administration first introduced the airline fee disclosure rule back in September 2022. It requires airlines and online travel agencies to disclose fees for seat selection, checked baggage and other add-ons upfront alongside the airfare, rather than adding the costs at checkout based on a customer’s selections.
