Slightly related question/sanity check here:
if Miles all expire end Feb 2018 (as is the case for Mrs AITF who lost her FTL status a few years ago), then these are still valid for a reward booking made in January 2018 for a flight in Deccember 2018? i.e the time of booking is more important than the time of travel relative to the expiration date of the mlies...?
