I have heard some rumors that Mexicana went out of Star Alliance because it will become part of the One World alliance witn American Airlines.
That doesn`t make sense to me. IF Mexicana quit the Star Alliance because of disagreements with UAL over routes, why change to One World and AA?
On another note I thought Aeromexico was planning to join One World ...
Panama Jack hit the nail on the head, if the figures make sense then ...
