6. Dress up
You are wrong if you think that you need a night gown. What works for sure is a business suit combined with a nice pencil skirt and silky blouse. Look as if you’ve been recently browsing the FT in the executive lounge. Match the colors and be stylish. No doubt some makeup should also be applied. Flight upgrades are offered to those who LOOK as if those upgrades exist for them. Do not miss your chance – put on your Sunday best, smile and be self-confident.
