Good question analise

I have only seen five kits (BA, AA, TWA, DL and QF) and they really have varied.

my dream kit would include-
a better toothbrush
eye cream
some sort of calming balm- aromatherapy for the temples
better earplugs than currently provided
smaller socks for women
a shoe mitt for buffing up my boots
aspirin or ibuprofen for my headache that I always get
writing paper or a postcard of the routing

what I like-
the current american airlines business class kit- I really like the origins line, especially the lip remedy

the delta l'occitane stuff, but i could do without the tin it came in- good for christmas cookies, not good for schlepping around

what I don't need:
a hairbrush - I have short hair and don't need one or want to lug one around
mouthwash- not always necessary
