A new club
Do you fly first class or business class internationally? Do you keep the amenity bags? Do you fly economy class internationally and nab an amenity bag left lying on the seats/floor? Do you have a cabinet/cupboard/box full of airline amenity kits? Do you have more than 17 different eyeshades, 12 pairs of airline socks and 9 sets of airplugs?
If so then you are eligible for membership of the newest club, AAKA – airline amenity kits anonymous.
