Earning triple miles with new virgin cc

Hi all
I have just had an invite to change my Virginmoney MBNA mastercard to MBNA AMEX with virgin, and as a bonus they are offering 3 miles per £1 spent when spent with virgin holidays or virgin atlantic before July 2007.
Now it so happens I am planning a great escapade next Jan, but it looks like this has to be purchased from the Great escapade website - the terms of the card say that only purchases direct from Virgin atlantic and Virgin Holidays get the triple miles.
Anyone know if I can buy Great escapade tickets from Virgin?
Thanks a lot
