We have prepared this definitive guide to help more people learn about this incredible deal. Are you experiencing problems fitting airplane seatbelts? Worry no more! Here is what an airplane seatbelt extender can do for you.

What is an Airplane Seat belt Extender

A seat belt extender is an extra piece that goes between the ends (male and female) of a standard seat belt to provide more room by adding a different length to it. Overweight people and pregnant women, in most cases, require these extenders to grant them utmost comfort. No matter the reason for the flight and the destination, you will mostly need this piece. The airplane seat belt extenders were initially designed for obese and oversized people to find the comfort they wanted, especially in those long transoceanic flights.

An airplane seat extender was initially designed to help add an extra length. This is to say that they should only be used when the standard seatbelt won’t fit comfortably and not for any other reason.

Who requires an airplane seat belt extender?

Originally, seat belt extenders were designed for:

  • Large-sized and overweight people who have problems fitting the standard seat belt and feel embarrassed to ask for an extender.
  • Overweight passengers who do not wish to double-spend by buying an extra seat to get more room.

Are airplane seat belt extenders universal?

All airplane seat extenders are not universal. However, most airlines use the same type of seat belts. Type A universal seat belt extender is compatible with most airline seat belts and works on most commercial and international airlines.

Types of Airplane Seat Extenders

As aforementioned, an airplane seat extender is an extra piece that adds length to the standard seatbelt. There are two main types of airplane seat belt extenders.

Type A extension

Type A airplane seat belt extension corresponds to most airlines. This is to say, this type is compatible with most airline standard seatbelts. It fits 99.99% of airplane seatbelts except for Southwest airlines airplanes.

Type B extension

This is another basic type of airplane seatbelt extension suitable for specific airlines. The type B extender is a Southwest Airlines seat belt extender and other seat belts that correspond to them. Southwestern airlines stand out from other airlines for having different seats and seatbelts. You will need a Southwest seatbelt extender because other extenders are not compatible with the seat belts.

Using An Airplane Seat Extender

The fundamental idea behind using an airplane seat belt extender is quite simple. You either connect it to the seat and surrounding areas using other means or slip it over the standard seat belt. However, it is easier said than done. It may be surprisingly tricky to determine how to use your extender. With different seat belt setups for different airplanes, it may seem easy in theory, but it may be complex in practice. Since extenders are meant to add an extra length to the existing seat belt so that you can be comfortable, you have to be careful not to fit the extender too tightly.

Even so, you also have to make sure that your seatbelt is firm around your waist so that it can hold you in place. Most passengers have problems determining the best airplane seat belt extension fit that will not be too tight or too loose. You realize that connecting your seat belt extender is worth your tightness and practice is necessary before your next flight. You will need to get the best way to make your seatbelt as comfortable as possible by getting a feel of how tight it is tight enough.

While connecting the extender, make sure you hear the snap sound of the belt and buckle coming in contact. This is a sign that they have perfectly connected your seat belt extender.

Legality of Airline Seat Belt Extenders

Most people have been asking whether airplane seat belt extenders are legal. Well, seat belt extenders are legal, but this should not be the end of the story. The Federation Aviation Administration, FAA, since 2022, has been trying to crack down on the seat belt extenders that are permissible and keeping safety regulations.

Before buying any product, conduct due diligence to make sure it complies with the FAA safety regulation. One fundamental FAA rule is that the seat belt should not interfere with adjacent seats. However, the FAA is not clear about what constitutes significant interference of a seatbelt extender. This seems intentional as it gives airlines the leeway to choose the type of seat belt extender they approve for use.

Every airline also has its airline-specific guidelines regarding seat belt extenders. It is therefore essential to understand FAA regulations and the specific rules of the airline you are using before making a buying decision.

Tips for Asking for an Extender On the Flight

There is a stigma that comes with purchasing an extra seat or asking for a seat belt extender on a plane because you are plus size. For this reason, most plus-size passengers will choose to carry their own unregulated and, in most cases, unapproved seat belt extenders or pretend as if the belt fits properly. Both of these options are unsafe and risky should something happen. To make things a little bit easier for you when asking for an extender from the flight attendant, we have the following tips from you.


It is easier to find your seat if you board among the first people and comfortably attract the attendant’s attention. This way, you will be able to ask for the extender without any fear of judgment. Pre-boarding also gives you alone time with the attendant to ask for the extender before other passengers get on board. Pre-boarding also allows you to choose the most comfortable seat for some airlines like Southwest.

Ask For The Seat Belt Extender As you Board

After creating this lone and conducive environment with the attendant, go ahead and request the airplane seat belt extension. Things usually move relatively slow when people are boarding and trying to find space for their luggage. Use this time to talk to the flight attendant and request an airplane seat belt extender.

Select An Aisle Seat

If you are worried about receiving the extender when everyone is watching, sitting in an aisle seat makes this discrete for you. When requesting an extender, do not focus on the embarrassment but on your safety.
