AA is only changing leg room in coach class on 757's and A300. Most business routes are flown on other aircraft. Rumor has it that the 757's on business routes will not have leg room changed. The A300 is primarily a tourist aircraft to the Caribean and will probably have less room.

As for the transcon 3 class, I can't comment directly. 2 class cabin service on AA is excellent - particular the 2-3 hour or longer dinner hour flights. I'm not sure if the upgrade on non-dinner flights are worth it unless the flight is particularly crowded. The exit rows on AA aircraft have more seat pitch than F on other airlines so, powerports, and AA will try to keep the middle seat open for elites. Elites can reserve exit rows on line. With those features, the only difference in F is a wider seat and free drinks.

I don't travel much on transcon 3 cabin service flights. As for 2 cabin service flights, service is generally excellent on AA, particularly mid-con dinner flights. I'm not sure the non-dinner flights are worth it except on the most crowded flights.

As for the service recently on US, I can't comment on whether it has improved. I stopped flying US when they led the wave of passenger unfriendly changes. Remember the the non-refundable tickets that could not be changed and no miles for discounted tickets. All of these initiatives were started by US. I remember and won't fly US whenever it is avoidable.

As for AA, they have led the way in passenger friendly changes. For example, AA was the first airline to change the handling of non-refundable tickets recently, the first airline to allow cell phone use in the cabin after landing, the first airline to install powerports throughout (almost) the plan, the first airline to announce rescheduling during Isabel.

All things being equal, we should fly on airlines that lead the pack in customer friendly actions.
