A recent decision by the 5th U.S. Circuit Court of Appeals has placed the U.S. Department of Transportation's regulation aimed at increasing transparency in airline pricing in limbo. The new rule, introduced by the Biden administration, mandated that airlines and third-party ticket sellers disclose add-on fees upfront to consumers. However, following a lawsuit from six U.S. airlines and industry lobbying groups, the appeals court halted the regulation temporarily, citing concerns that it may exceed the DOT's authority and harm airlines.

The halted rule, set to take effect in late April 2025, would require airlines to prominently display ancillary charges such as those for checked bags, carry-ons, and change fees from the outset of fare viewing. The court's decision allows airlines to postpone implementing these changes until the case reaches a resolution, providing them with a reprieve from modifying how they exhibit prices and fees to customers.

Despite the setback, Transportation Secretary Pete Buttigieg affirmed the DOT's commitment to advancing price transparency efforts. Buttigieg emphasized that protecting passengers from undisclosed fees remains a priority for the administration. He criticized the airline industry's resistance to fee disclosure, stating that the argument claiming it would harm airlines irreparably is unfounded.

While the fate of the upfront pricing rule hangs in the balance, the current suspension signifies that the regulation will not come into effect in the near future. Consumers are advised to continue scrutinizing fare rules when booking flights, especially regarding additional charges for services like carry-ons, seat selection, and other airline-specific fees. Airlines, including some budget carriers, have already taken steps to remove certain ancillary fees to improve customer satisfaction, despite most major U.S. airlines raising checked bag fees in 2024.
