Two Seat Safety and Comfort

Are airline seats designed and tested for comfort and safety in the case where a person of size is occupying two seats? From personal experience, I can say that it is very uncomfortable to straddle two seats. Typically there is a hard ridge in between the seats that is directly below the tailbone. The raised armrests often protrude and contact the spine. The seat belt receptacle is directly underneath the person sitting this way.

Airline Person Of Size Policies

Each airline has a policy for persons of size. The airline policies vary widely. Southwest Airlines has a progressive policy and is continuously improving their process for persons of size. Alaska Airlines has a clear policy. The remaining airlines in the U.S. top five, approach the issue with varying levels of concern for persons of size and quality of their policies and process.

Your Rights

All travelers should know their rights and responsibilities relative to the seating policies of the airline. A person meeting the airline definition of person of size may opt to purchase one or more extra seats in advance. Alternately, if they board the aircraft and it comes to the flight attendants attention that they are a person of size, if there is an available seat they will be accommodated. If not, the policies say they will be de-boarded.
