What do you mean? What else do you need for a flight than what's in the kit? I expect the washroom has moisturizer.

I can just think potentially socks. But from experience, airline socks are so bad they may as well not give them. Slippers would be nice.

Amenity kits at some time morphed into "goodie" bags. Then they went downmarket, making them cheap goodie bags. It's great that they are reverting to solid amenity kits.
