Reading the fine print...

"In addition to your sweepstakes entry, when you travel with threee or more different oneworld airlines on an eligible ticket* between October 1, 1999 and December 31, 1999, you'll earn thousands of bonus miles"

* = The flight must be marketed and operated by a oneworld airline

Question: "An eligible ticket" ? Does this mean that you have to hit 3 or more oneworld airlines on a SINGLE ticket ? Can't see how AA can tell if all flights came from a single ticket or not, but the wording is peculiar...
