We might get confirmation as to what the first 77W route is by the end of summer.mif I were a betting man, I'd say DFWHKG, but that's based just on my opinion.
I also do expect AA to add a third trans-Pac route from LAX next year, and I'd guess it would be Beijing. Maybe Osaka or Nagoya if the 763 pilot contracts allow it (both are bordering on the 12h pilot limit).
The four gates at TBIT need to be triggered by construction of a certain amount of gates at TBIT (I forget what number that is), but AA seems pretty confident that the clause will be triggered.
Also, a massive remodel of Terminal 4 has begun and will last a year, which will cause some gate issues for the next year.
