I was just wondering what the best way to go about doing this was.

I purchased an E+ subscription for the upcoming year, which means that I need to apply my MP account number when I book (which doesn't have any status associated with it).

I'd like to apply my Star Gold frequent flyer number (with Asiana) so that I can get the checked baggage/priority boarding/club access.

I understand that my E+ seat shouldn't change if I change my FF# after booking, but that if there are any equipment changes then I'm outta luck.

So is the best way to do this to change my FF# at check-in (before checking in, so that I get the free checked baggage)?

Thanks for the help everyone
