I find that I can work in coach.

Working on a laptop is much easier on AA more room throughout coach flights, because you can put your laptop on the tray table and still use it, even if the person in front of you reclines. I was on a pre-MRTC flight AA JFK-LHR a few years back, and using a laptop was almost impossible. When the guy in front of me reclined, I had to pull the laptop all the way toward me, so that it was just about touching my stomach. Then I had to type on it and manage papers at the same time - not too comfortable, but I didn't have a choice.

I find I can do a couple hours of work on a plane. But, wearing noise canceling headphones makes me much more effective, less tired and allows me to concentrate better. I also tend to feel better when I get off the plane on flights where I wear the NC headphones.

As for not bothering neighbors - I just try not to shuffle around too much. Planes are pretty loud, so unless you have an annoyingly loud keyboard, the clicks are pretty muted. You might also want to see about getting a seat assignment with the seat next to you empty, even if it's in the back of the cabin. Of course it's usually louder back there, so the NC headphones are even more important.

Also, if you want to work for any kind of length (and it sounds like you do if you're going to be on ten hour flights), make sure that (1) you get a power adapter and (2) you're flying on a plane with power ports AND you're seated in a row that has them. On AA most of the aircraft have power ports, but only selected rows in coach (usually all of the "premium" seats in the first few rows of coach, then selected rows througout the rest of the cabin).
