I think I'm getting a bit worried over nothing but through Tesco and Marriott and a few flights this year have managed to get just under 100K miles. Looking at my account though says my membership year end 8th Sept and card expires 8th Oct.

I'm assuming that means I'll loose my tier points I collected this year (which isn't much) but I'm not going to loose any points am I. Last flight was April?

Many thanks
