Regarding remote/jump/AAA.
Worldspan allows you to work in a differnet PCC in one work area, while the other work area could be in a third PCC.
Sabre allows the same, and they allow you to have 2 Sabre windows open (for example, 1 from PCC A, and one for PCC B).
Amadeus on the other hand, you can only have 1 Amadeus open, and when jumping, all areas gets jumps.
Someone has a workaround?
