No you are not.. I am chubby myself, but I think this is outrageous. Why should you move? There is a perfectly sensible solution to this problem. As usual, it is Southwest airlines which has provided the best customer focussed solution.

If there are spare seats, the overweight passenger is seated next to an empty seat and does not have to pay for another. (They may have to pay upfront and claim a refund). If the flight is full, the overweight passenger must pay for a seocnd seat at the same rate they paid for their first one. Under no circumstances would it be a requirement for you to move.

The bottom line is this. If the passenger cannot put the armrest down, then they should have to pay for another seat. This is a fair and objective measure and would not open the overweight passenger up to the capricious nature of the morons who work the front desk for airlines.

You have a legitimate complaint..but I suspect the wording of it may have contributed to their reaction. Fat people exist and your complaint is valid.. so there is no reason for you to be personal or obnoxious about the person. Just objectively write how your comfort was compromised, what you would like them to do about it and then ask them in future to ask the overweight passenger to move.
