According to reports in Thailand, Thai Airways Is considering banning people who they considered too large to fit into their new seats in their business class cabins.
Far from being seen as any type of safety or moral hazard, the decision apparently applies to people who have a waistline that is larger than 56 inches, and is needed to cause the seatbelts in the business class cabins have a new feature which is a seat belt airbag.
Apparently this seat belt airbag will not work with people who have a waste of this circumference, and as such they will be banned from flying with them.
