I'm a bit of a saddo and quite like Gatwick, I wouldn't say it was beautiful but from a seat in one of the executive lounges with the sort of complmentary food, drink & comfy sofas, as part of your entry it always seems fine to me if I have a Pimms in my hand.
Maybe it's what you get used to, I know it is a major hub and ultra modern but I really didnt like Miami airport and I think I must have been through Charles de Gaulle when the whole of the place was being ripped apart, hopefully its better now. As for Mombassa well, pretty Country but the less said about the airport the better.
