Book VX flight on a UK site?

Are there any UK sites where I can book a VX First class flight? Expedia and others I've looked at only do Economy.

I could book on their US site, but I have to pay on my Amex for my travel insurance to be valid, so want to avoid the FX fee.

TIA!

Just as I pressed submit I thought about Amex Travel. Their web site doesn't list VX, so I phoned and they can do them. They call it business class, but it's row 1 and 2.

If I booked online with VX it would be £228 on my Amex card. With Amex Travel it's £218.

I don't know why I always forget about Amex Travel.
