Anyone collect/use them? I've just had 20,000 points credited to my Amex account for hitting a new card spend target. I can exchange them for a £100 gift voucher for quite a few places or convert them to 20,000 Avios points. Which would be the best deal? I also already have 16,000 Avios points plus our daughter is going to use a referral link from me for an Amex card so that she can collect them but I will also get another 9,000 points for that. Any suggestions of what to do? Are they worth more than £100 if I used them at British Airways?
