The Hidden Fees Airlines Charge (And How to Avoid Getting Fleeced)

Here's what they're actually charging in 2025:

Checked Bags: $35 first bag, $45 second (Delta, United, American). Spirit and Frontier hit you for $50 when you pre-pay online. In May 2025, Southwest abandoned its 50-year "bags fly free" policy. The last holdout fell.

Carry-On Bags: Budget carriers charge $31-65 for overhead bin access. Spirit's cheapest fares don't even allow carry-ons—just one personal item that fits under the seat.

Seat Selection: Average preferred seat costs $33. Exit rows run $48. American charges up to $160 for extra legroom internationally. Southwest launches assigned seating January 27, 2026, expecting to make $1.5 billion annually from it.

Everything Else: Overweight bags (51-70 lbs): $100-150. Oversized (63-80 inches): $150-200. Priority boarding: $35. Printing boarding passes at the airport: $25. Changing tickets: $0-400.

In April 2024, the Biden administration passed a rule requiring airlines to show all fees upfront. The airlines sued. A federal appeals court put the rule on hold, where it remains. The DOT estimated transparency would save consumers $500 million annually. The airlines called it burdensome regulation. Translation: we prefer customers don't see the full price until after they've committed to the trip.

Check bags for free with the right credit card. Airline co-branded cards often include free checked bags. The Delta SkyMiles Amex, United Explorer, and American Airlines cards waive first bag fees for you and up to eight companions on the same reservation. Three roundtrips with one checked bag saves you $210 covering most annual fees.

Skip seat selection entirely. Set an alarm for exactly 24 hours before your flight and check in the moment it opens. You'll get assigned a seat for free. Traveling with someone? You'll likely sit together. Won't be your dream seat, but you'll get there just the same.

Pack like you mean it. One personal item is free on every airline. A properly packed backpack that fits under the seat can hold three days' worth of clothes. It's a skill worth developing.

Join loyalty programs. Free to join, and even low-tier status can mean free seat selection or priority boarding. You're giving them your email address to avoid paying $35. Fair trade.

Pre-pay everything online. Checking a bag or selecting a seat? Do it during booking or at least 24 hours out. Airport prices spike dramatically. Frontier charges almost double at the gate for bags you could've added online.

Airline credit cards work if you're not paying interest. A Delta SkyMiles Gold card has a $150 annual fee but saves you $70 per roundtrip in baggage fees. Three trips and you're ahead. Many travel cards also include TSA PreCheck credits ($85-100 value), airline fee credits (Amex Platinum gives you $200 annually), and lounge access. But if you carry a balance, the 20-something percent interest rate obliterates any savings. Pay it off monthly or don't play.

Airlines collected over $5 billion in baggage fees last year, another $4.2 billion from seat selection. Delta made $7 billion from its American Express partnership in 2024—more than from actually flying planes profitably. The system isn't broken. It's working exactly as designed. The advertised fare wins the sorting algorithm on Google Flights. Everything else is à la carte.

The golden age when a ticket price meant a ticket price is gone. What replaced it: a base fare that gets you from A to B in a seat you didn't choose, eating food you brought yourself, with bags you either paid for or strategically didn't pack. It's not dignified. But it's also not personal. The airlines would charge oxygen separately if they could figure out the optics. Until then, they'll settle for charging you to bring a suitcase.
