Tier Point Question - Sorry

Hello,
My membership year ends at the end of November.
My question is - if I take another flight (say during the summer), would my "year" start all over again? I doubt I will get to Silver status as I am only Red, but there are some plans for early next year where it might be possible for me to get to Gold if I can hang on to my tier points (8 of them) until January. I was thinking that if I booked another flight for a week somewhere, would that be enough to generate a new year?
Hope that makes sense!
Thanks

I'm not sure I've understood you completely, but for tier upgrades the membership years are irrelevant -- you just have to accrue the right number of TPs in a rolling 12-13 month period.

Miles are retained so long as you have any earning within a three year period. As said, TPs expire when your FC membership renews, so sorry there's no way to hang on to expired tier points.
