Some airlines are size-friendly with wide seats and ample legroom. Other airlines are increasing the number of seats on an airplane to increase profits, making seating more cramped with narrow seats and very limited space between the rows. Some airlines, such as Delta, American and United, have created “super economy” fares which limit seat width, legroom and limit carry on baggage.
The three main things that most affect airline comfort for a big passenger are seat belt extenders, seat space and restroom facilities.
How to Get More Airline Comfort for a Big Passenger
Seat Belt Extenders
If the seat belt on an airplane doesn’t fit you, you need to use a seat belt extender. All airplanes carry them — flight attendants use them to demonstrate how to fasten your seat belt. Airlines win points from their passengers for being discreet and polite with seat belt extenders. If you get a pre-assigned seat, you may be able to ask the airline or your travel agent to put an extender on the belt for that seat in advance. Otherwise, you can ask the flight attendant for one.
