Best: That time I was flying back to Madrid late afternoon so decided to have Wagamama’s for dinner
Opportunity to read crap magazines while I wait (German airports usually have a good range of music magazines)
Going abroad is nice
Worst:
Far out of city centre
Anxiety about missing plane makes me get there about 6 hours early
Expensive shops
Crap/expensive food (other than above mentioned Wagamama’s)
When people are rude to cabin staff who are just trying to do their jobs (saw a man have ever such a tantrum at a woman who told him the flight was busy and would have to have his bag in the hold)
