There are several types of seat belt extenders, both for vehicles and airplanes. Do you know if you need one? And, if so, what type or size you need?
Depending on your body shape, you may need a seat belt extender for vehicle or airline travel. Standard length seat belts are designed for the traveler who weighs up to about 215 pounds. If you weigh more than 215 pounds or if you carry your weight around your hips and stomach, you are probably a good candidate for a seat belt extender.
