As of May 2025, the airline baggage fee rules 2025 have undergone notable revisions across U.S. carriers. Regulatory shifts from the Department of Transportation (DOT) now require airlines to disclose full baggage costs upfront—an effort to cut down on hidden charges and enhance pricing transparency. Major airlines have updated their policies to reflect these federal travel regulations, creating a diverse range of fee structures for checked and carry-on luggage.
Understanding how each carrier handles luggage fees is now crucial for any traveler hoping to avoid unexpected charges or take advantage of more affordable packing options.
Baggage Policy Changes Across Major U.S. Airlines
The most significant baggage policy changes in 2025 involve a mandatory 48-hour fee lock-in post-booking, clearer fare class disclosures, and detailed itemization of any airline fees during checkout. While some airlines have maintained flat-rate structures, others, like Frontier and Spirit, continue to apply dynamic pricing based on route, season, and demand.
JetBlue and Delta, for instance, now allow one free checked bag for domestic main cabin passengers—a shift designed to win back budget-conscious customers. Meanwhile, Southwest remains consistent with its two-free-checked-bag policy, reinforcing its customer-friendly brand positioning.

Budget carriers may appear cheaper initially, but added costs for basic carry-on or checked bags often outweigh initial savings.

Also, note the expanded use of AI-powered fee calculators on airline websites, helping passengers simulate trip costs based on real-time travel regulations and their packing preferences.
