The era of the all-inclusive airline ticket ended long ago. But 2026 brought a new wave of fees that crossed lines that even seasoned travelers didn’t expect. Carriers are now charging for things that were quietly standard for decades — and if you don’t know to look for them, you won’t see the charge until it’s already on your card.

The New Fees Most Travelers Are Getting Hit With

Seat selection fees on full-service carriers

American, Delta, and United have all expanded their seat-selection fee tiers in 2025–2026. What used to be a free middle seat that passengers avoided is now gated behind basic economy restrictions that charge for any specific seat choice. On American’s basic economy fares, selecting any seat at booking costs $9–$45 depending on route length and seat location. The free option: wait until check-in and accept a random assignment.

Carry-on bag fees — now spreading to legacy carriers

American Airlines became the first legacy carrier to charge for carry-on bags on its lowest fare tier, a move that caused significant backlash but little change in booking behavior. On basic economy tickets, you’re limited to a personal item (under the seat). A carry-on that goes in the overhead bin costs extra — $25–$45 depending on how far in advance you add it.

Flight change fees — back in some forms

Airlines eliminated change fees during the pandemic and marketed it heavily. Many have now quietly re-introduced them on the lowest fare classes. You can still change a main cabin fare without a fee on most major carriers, but basic economy changes — on routes and carriers that allow them at all — now carry penalties of $49–$99 that weren’t there a year ago.

Family seating fees that violate DOT guidance

The DOT has issued guidance stating that airlines should seat children under 13 next to an accompanying adult at no additional charge. The guidance is not yet a firm rule, and some carriers are still charging families to select adjacent seats. The DOT proposed a formal rule in 2024 — follow the status of that rule before your next family booking to know what you’re owed.

How to Avoid the Fees That Are Avoidable

Carry-on bag strategy:

• Book main cabin or higher — the fee only applies to the lowest basic economy tier
• Hold a co-branded airline credit card — most waive the first checked bag, and many waive carry-on restrictions on basic economy fares
• Allegiant and Southwest still include a free carry-on with every ticket as of 2026

Seat selection strategy:

• Check in exactly 24 hours before departure — airlines often release blocked seats at check-in
• Gate agents frequently reassign seats for free when flights aren’t full
• Use ExpertFlyer or Google Flights seat maps to see which seats open up close to departure

The One Fee That’s Actually New and Almost Nobody Knows About

Several carriers are now testing and rolling out fees for priority boarding that go beyond the traditional elite tier system. On Frontier, Allegiant, and Spirit, “Zone 1” boarding access — which used to be de facto free for anyone who arrived early — now costs $7–$15 per flight as an add-on. It’s positioned as an upgrade, but what it really does is make early boarding a paid perk rather than a first-come benefit.

The reason this matters: early boarding used to be the budget airline hack for guaranteed overhead bin space. With Spirit and Frontier charging for it, travelers who add a carry-on bag but skip the boarding upgrade are increasingly arriving at an overhead bin that’s already full — leading to gate checks, delays, and exactly the kind of airport stress you bought the budget ticket to avoid. If you fly budget, add the boarding fee or check a bag. The middle option no longer reliably works.

The Airlines Adding Fees in 2026

The new fee categories emerging from airlines in 2025 and 2026 include: seat selection fees applied to tickets that previously included standard seat assignment at booking, carry-on bag fees extended to main cabin fares (not just basic economy) on some carriers, and ‘convenience fees’ for booking through the airline’s own website rather than through a travel agent or OTA. The last category is counter-intuitive — airlines are experimenting with charging customers for direct booking to offset agency economics — and is the most likely to confuse travelers who assume booking direct always avoids fees.

The practical response to fee proliferation is to calculate total cost rather than base fare when comparing tickets. A $189 base fare with $35 carry-on, $25 seat selection, and $10 booking fee is $259 — more than a $230 fare that includes those amenities. Google Flights and Kayak now display fee-inclusive prices for most carriers, which makes the comparison more transparent than it was three years ago. The travelers who understand that the base fare is the starting number rather than the ending number avoid the sticker shock that the fee structure is designed to create.
