I got 4 when I reached GM mid last year with an expiration of 1/31/2020 and then another 4 when I reached PM in November with the same expiration of 1/31/2020.
Oddly the first 4 show a of scotch/bourbon and the next 4 have 3 with wine and 1 with scotch/bourbon pic.
I have never used them since I am typically on an international flight with free alcohol and when I fly domestic I am mostly put in C+...
