I would really stop moaning. Before you think 'it is a short flight' imagine there is a 3 hour apron delay (thunderstorms etc.). Just think how much more comfortable would be in F than in Coach.

Mitigation plan would be to talk to your neighbors to swap seats. As this is a non- meal flight, I would be willing to swap as long as I am still in the Big Seat. I will not be on your flight, though...
