I agree about the MD-80, that a seat more up front in the coach cabin is prefered if you can't get First Class of course. The MD-80 (AA of course !!!) is a very nice aircraft to fly on, very pleasant especially now that they all have the new interiors. When you are seated up front, you barely hear the noise of the engines when at full power during take off, and when you climb you hear almost nothing and the aircraft rises quickly. An other quality of this aicraft is that it handles itself well when dealing with turbulence.
When I get a Super 80, I don't choose an A or F window seat according to the number or seats next to me, it doesn't matter whether there is one or two seats next to me. I choose an A or F seat according to these things: the direction of the flight whether North or South, the area I may see according to the direction of the flight, and the time of the day. I think on what side of the aicraft I should be seated if I want to have a nice sunset or sunrise, assuming that the flight is at the end of the day or early in the morning. All those factors come into play when choosing an A or F seat. On a recent trip to the United States, I flew on three Super 80's, one from ORD to FLL, one from FLL to LGA and one from LGA to ORD (connecting on a 767 to BRU). All were nice flights.
I just flew on a 767-300 from ORD to BRU and I was seated in an exit row. That's the best seat to have in economy if you really want to strech out, however the disatvantages are that you are seated just over the wing which prevents you from seeing below and you have all the noise of the engines coming right at you. If you take the exit row, keep in mind that YOU take the responsibility of knowing how to open the overwing door in the event of an emergency landing or an aboarted take-off.
More Room Through Coach on AA? Not always. I flew on a Fokker 100 from DTW to ORD and the aircraft did still have the old seats, the light blue seats with the gray rectangles. This looks like the Fokker 100's have not been refurbished. I was seated in First Class, which still had the old brown leather seats.
Have a nice flight wherever you may go.
