The Department of Transportation has proposed rolling back the rule that requires airlines to display a ticket's full price — including taxes and government fees — from the moment a traveler starts searching for flights. Under the proposal, filed as docket DOT-OST-2025-0831, airlines could instead show just the base fare up front, with taxes and fees added in later at checkout.
What changes for travelers
Currently, federal rules require airlines and ticket agents to display the total price travelers will actually pay, taxes and fees included, whenever a fare is quoted. The DOT's proposal would let carriers instead advertise a lower headline number and reveal the rest of the cost later in the booking process — closer to how many other retailers price add-on fees.
