I’ll start off:
Best:
Hong Kong: apart from the crap wireless it is a breeze
Cork: right in middle of the city it is small but perfectly formed
Honolulu: it’s a semi-alfresco airport with a sea view and cocktails
Worst:
Tel Aviv: Not so much the building but the hours of questions and harassment every time you enter or leave.
Fuzhou: I’ve spent more hours than I care to remember in this shit-pit. Where they charge 50yuan for a cold cup of Nescafe!
Bangkok (the old one): awful brown terminal, nothing to do, miles from the city, why?
