Flying While Fat: Airline Policies, Seat Tips, and How to Actually Enjoy the Flight

You've done the research. You've booked the hotel, planned the whole trip. And then you get to the airport and realize nobody ever told you the part that actually stresses fat travelers out the most: what happens on the plane.

I'm not going to sugarcoat this. Airline policies for customers of size vary wildly depending on who you're flying, and not knowing yours before you board can cost you your seat. Literally. I've seen people get pulled off flights. I've seen people charged fees at the gate that nobody warned them about. And I've talked to fat travelers who white-knuckled the entire flight because they didn't know they had options.

So here's the breakdown (airline by airline, tip by tip) written by someone who actually flies in a fat body and plans travel for people who do the same.

The Airlines That Will Refund Your Second Seat

Let's start with the good news. Some airlines have genuine customer of size policies that include a refund for a second seat. Here's how they actually work.

Southwest Airlines

Southwest has one of the more well-known policies, but it changed in January 2026 and a lot of people haven't caught up yet.

If you need a second seat, you can get a refund, but only if at least one seat on your specific flight departs open, and both seats must be purchased in the same fare class. That same-fare-class matching is the new requirement, and it's a hard one. Day-of accommodations are no longer a thing.

Submit your refund request within 90 days of travel.

Alaska Airlines

Alaska will refund the second seat, but there's a catch that catches people off guard: every single Alaska-operated segment on your trip has to depart with at least one open seat. Round trip means both legs have to qualify. If one segment is full, the refund is voided for the entire trip.

Call 1-800-252-7522 to book, the call center fee is waived for customers of size. Submit your refund request within 90 days.

Air Canada

Air Canada will refund a pre-purchased extra seat, but you'll need a doctor's note confirming your need for additional space, and it has to be submitted before travel. Contact Air Canada directly to book and get your documentation in order ahead of time.

WestJet

WestJet is genuinely one of the friendliest policies in North America for plus size travelers. No doctor's note required. Purchase the extra seat in advance, request your refund after travel, and that's it. No hoops.

The Airlines With No Refund (And What to Do Instead)

These airlines either don't offer refunds for a second seat or have limited policies. Knowing this ahead of time means you can plan around it instead of being surprised at the gate.

Delta

Delta doesn't have a refund program. They encourage (but do not require) purchasing a second seat in the same fare class. What they do offer is a range of upgrade options: Delta Comfort+, Premium Select (seats are 19 inches wide), Delta First, and Delta One. One thing to note: Basic Economy tickets cannot be used to purchase an extra seat.

JetBlue

JetBlue requires an advance extra-seat purchase and offers no refunds. Their EvenMore seats give you more legroom, not more width (important distinction.) Core economy seats run 17.8 to 18.25 inches wide, which is actually among the widest in U.S. economy. If you're going business, Mint class seats are 20.5 inches and up.

Frontier

Frontier has the strictest policy of any U.S. carrier. If you cannot lower both armrests, you are required to purchase a second seat. Refunds are only available within the 24-hour booking window after that, you're on your own.

The most comfortable option Frontier offers for fat travelers is their UpFront Plus rows, which include a blocked middle seat. If you're flying Frontier, that's the move.

British Airways

Extra seats on British Airways must be booked by phone only. Minimum charge is £40 for short-haul or £300 for long-haul, and there are no refunds. Also worth knowing: World Traveller Plus (their premium economy) has fixed armrests, which makes it incompatible with extra-seat bookings.

Pro-Tips for Flying Fat That You Need to Know

Knowing the policy is step one. Here's what to do with that information.

Before you even book, look up the seat width. SeatGuru.com breaks down seat dimensions by airline and aircraft. Read the airline's official customer of size policy before you purchase. Knowing how they define "needing" a second seat before you're standing at the gate is the difference between a smooth trip and a nightmare.

Check the seat map the morning of your flight. Open the airline's app and look at what's available next to you. Most airlines let you change your seat up to an hour before departure. If there's an empty row or a middle seat open, move. You don't have to wait for someone to offer it.

Take the gate situation seriously. If an airline decides at the gate that you need a second seat but none are available, you can be removed from the flight and placed on the next one. I don't say that to scare you, I say it so you plan ahead and don't leave this to chance.

When in doubt, book First Class. I know it costs more. But First Class gets you priority boarding, priority check-in and baggage, complimentary meals, and on longer flights, wider seats and more space across the board. On certain routes, the peace of mind alone is worth it. 

Flying in a Bigger Body Shouldn’t Discourage You From Traveling

The reason most fat travelers dread flying isn't the flight itself. It's the not knowing. Not knowing if the seat will fit. Not knowing your rights if something goes wrong.

That's exactly what I do: I plan trips for plus size travelers who want to show up and actually enjoy themselves, not spend the whole experience managing logistics that nobody warned them about.
