I received 4000 Melia Rewards points last year in the British Airways promo. The points are about to expire in a month's time. I tried cashing them out to Amazon Vouches and Avios but it doesn't work, probably because these promo points are ringfenced. Is there a way to extend these Melia Rewards points? I am not particularly interested in buying more points, considering I have little use for them at this time. But if that is the only way possible, what is the lowest amount of points I can buy?
Thanks in advance for your help.
