My husband and I live in Korea, as he is in the military. We travel to my home country (UK) in one week, and I'm starting to worry about little details.

We booked the tickets under the US site (from Korea, to China, to England.. Not from the US to England) because the Korean site wanted a Korean address for the credit card used. Well, the US site was having issues with out card, so we just checked out with paypal. (We didn't log in, we just checked out with our credit card via paypal to pay for it.) The Korean site doesn't have that option, and on the site, it's said they might want to see the card we checked out with. Well, if we were on the US site, they wont know we checked out via paypal will they? We have everything we need, like our tickets, but I've read on this forum that Asia asks for the card a lot of the time, like it said on Air Chnas site, and I don't want to be denied boarding because I want on the US site and paid via paypal.
