Well, I got to Silver in August 2014. When I received my card in the post, the expiry date printed on the card was 03/2016, and on the website it says the same – 31 March 2016. My TPs expire annually on 8 February, so I just assumed the card is valid for the whole of the next TP year, plus a month. Is that wrong?
It’s been a slog by the way… my company will pay for only the cheapest fares, and I fly UK domestic only (mainly LHR-EDI): 1080 TPs equate to exactly 108 flights in a TP year, but I have no chance of ever getting to Gold.
