Getting ready to book the next couple of holidays......
Don't really understand FC upgrades. We have 12500 miles each after our last trip to CUN. We have changed all our outstanding Tesco vouchers up to FC miles and my husband has just opened a Virgin credit card. The idea was that we would maximise our points by paying for the holidays on the card and then paying the card off within the 6 month interest free period.
Now my query is, is it possible to buy economy flights now and then later upgrade to PE with points?
The flights that I am looking at currently don't have a PE upgrade available, I wondered if that's because I'm too early? The flights are LHR - LAX during the school summer holiday next year and LHR - DXB next Christmas.
