Is there any credit given for members from another airline, Qantas, who have accrued points flying BA and AA towards that freq. flyer program? I would like to join BA or AA because I can't move to gold with Qantas because I do not fly Qantas (based in the US and UK) but unsure the value of AAdvantage or BA Exec. Club if I have to start at 0; Star Alliance may be a better option.
