I'm trying to help a friend in China arrange a multi-city visit here in the USA.

I arranged everything have have Farelocks in place.

The plan was that I would buy the tickets for her, and she pays me back.

Or... once I had everything set on website, she could sign in and pay.

Maybe not so easy?

Sounds like she cannot purchase the tickets using her (China) credit card because I paid for the farelock using my (USA) credit card?

And I cannot do the fare lock in RMB using my USA credit card.

And there is some risk that she'll be denied bording if I pay for the tickets using my USA card?
