I don't fly all that often, and chances are, I will not be flying anytime soon. I could make one small suggestion though. At check in, ask to see how booked the flight is and if there might be another flight at a different time in the day that has fewer passengers. The last time that I took I did that, and ended up moving from an over booked flight to an earlier flight with only 10 passengers. It was kind of nice having most of the plan to yourself. The flight crew let us sit wherever we wanted and felt most comfortable. It does mean the possibility of spending more time at the airport, but your flight could be a lot more comfortable.
