Keeping miles from expiring
I haven't flown F9 in a while and noticed on last months email statement that I had some miles that were slated to expire at the end of this month. I'm not flying F9 anytime soon, so I redeemed some miles for a magazine. Does this extend my miles (it does in other programs)? I only ask because today I got a notice that I had miles that are about to expire. My account activity shows the debit for the magazine subscription. Tried searching, but didn't find any recent threads.
