The body discomfort of economy class aircraft passenger is associated with flight duration. Further studies concerning how to best provide comfort to long haul economy class aircraft passengers are needed. The survey presented in this paper will beneficial the aircraft passenger seat designers to facilitate future design and evaluate seats that able to reduce body discomfort during long haul air travel.
