I will be making a trip to Brazil approximately Feb 28 to Mar 10, 2014. The miles will be just enough to earn Aegean gold status (and thus Star Gold) if credited to Aegean. There is a convenient US Airways flight. If I book the flight and use my A3 frequent flier number, what happens if and when US Airways leaves Star Alliance in early 2014. I assume I would not be able to accrue on Aegean and I'd have to apply a OneWorld frequent flier account to the flight. Is that correct?
