I've been looking around and so far have found that the
new AA OneWorld Electronic Timetable answers many of my questions in that it allows you to select an origin or destination city, leaving the other one set to "-All Airports-" and you get a listing of where flights from/to that city go to or originate from. It also shows what airline operates the flight - big help to make sure you get the "right" flight number on the reservation/ticket.
A big help in planning RTW trip routing. Now if it only had tier points and mileage at the same time.
A bit frustrating, though, as it won't do multi segment routing like the CX timetable will.
Also thx for advice on "great circle mapper" site - that is a wonderful help!
