My son is an "Explorer" and his FB miles were due to expire originally in July, then by the end of this year because of the COVID (he did not have any flight activity since Fall 2018).

With the recent pandemic developments, I was about to prepare a message for FB asking for another potential extension. I made a quick check on his FB account and I saw that expiration deadline had been extended until end of 2021



This is the first data point I can see on this topic in this forum/thread. I hope this is also valid for all other Explorers in the same situation than my son's.
