Just wanted to share as I'm really excited!! We had some Virgin Flying Club miles already, but not enough to do anything with. Had a look on the Tesco Clubcard website yesterday, and about £50 in Clubcard points will convert into enough Flying Club miles for an upgrade one way!! We're not travelling until next Oct so have loads of time, and are just going to start spending (only things we would have bought anyway, food/petrol/clothes etc) on our Tesco credit card too. We were really dithering about paying for the upgrade on the flight home but it's something like £900 for the four of us, and now should hopefully get it for nothing, yay
