My wife has a ton of Amex points and would like to use them to buy an upper class round trip from LAX to LHR so she can visit me here in London.

Trip will be first week of September and for one week or 10 days.

I think she would prefer Virgin.

How easy is it going to be for her to make the arrangements and how many points would it take for her to cover the full cost?

Any additional tips greatly appreciated!

We have never done this before and it is a bit daunting.
