Sorry if this is stupid question, but is it possible to credit miles to one frequent flyer program yet still use the benefits of your status in another frequent flyer program? I'm flying US Airways soon and would like to credit the miles to Dividend Miles but I'd like to use my Air Berlin Gold status for the lounge access and possible checked baggage. Is this possible if the Air Berlin frequent flyer number isn't in the booking?

Thanks for any help in advance...
