Another tip I can offer.
Earlier this year I received an email from an airline I travelled with approximately two years ago saying that I have points expiring about a month or two later.
The airline was Etihad. I do not have any loyalty to one airline, I go for price and convenience when travelling. So, I don't really accumulate a large number of points with one airline.
Anyway, I went to their website to check out their online shop. There was nothing I could see that I really wanted or needed. Nearing the end of my perusal of their site I found you could exchange the airline points for Amazon gift vouchers.
Firstly, I transferred my wife's points to my account giving more points to spend in one transaction, then I exchanged the points for Amazon gift cards. By doing this it opened up a much larger range of products to obtain.
I ended up with a few hundred pounds sterling worth of Amazon gift cards.
If anyone has points which may be expiring and you are not likely to use them for travel, check out other options I have mentioned.
