The sleepwear in First Class is by far the most bizarre thing about the whole experience.

I've never understood why First and Business Class that are so clearly mainly used by people travelling for work don't focus more on the business aspect. British Airways call it "Club" which I'm sure can only make it harder to be approved by finance. American call it "First".

In the main lounges provided by American Airlines there is often a person whose job it is to provide unlimited champagne but not a comfortable place to respond to emails.
