I am United Premier Gold (*A Gold) and will be flying Air China (*A member) though want to use Aegean FF # since they have rumored easy lifetime *A Gold membership.

If I credit my Air China flight to the non-Gold Aegean FF#, can I still flash the United Premier Gold (*A Gold) credentials and get benefits, like priority check-in and lounge access?

I suspect this is one of those "your mileage will vary" type of situations. I assume that technically I don't qualify for the *A Gold goodies, though haven't combed through all the terms and conditions to officially confirm it.

I'm sure this has come up many times before. What's the consensus?

Thanks.
