Since I don't drink alcohol on flights, I don't get passionate about f/c seats on short flights (< 1 hour). On this particular day I had already spent 9.5 hours flying in from Europe and quite frankly stretching out over a whole coach row was far more appealing to me than turning down more booze up front. Eliminating four more hours of dead time was the big draw.
Don't ever expect me give up my f/c seat on a west coast trip, though!
