I am a big guy, though still able to fit into an AA seat without seatbelt extender; I do not spill over into the adjacent seat. However, I was thinking, if a person buys 2 seats on an AA flight in order to accommodate the person's physical size, can said person get Aadvantage credit for both of the seats?
This could be a relatively lucrative way to maximize the benefits of a MR if so...
eta: I did a search, but the threads relating to Pax Of Size seemed to all relate to FTers looking for compensation for having had to sit next to (practically underneath) one.
