My Best list.....although it depends on where you are going, and what terminal etc.
1. Zurich
2. Frankfurt
3. Schipol
Never been to Austriche, but on Frankfurt, it's O-KAY like.
Nice and modern, efficient and all that lark.
But it's grey-blue tones make it all very dark, seed, clandestine.
I'm waiting for Harrison Ford to emerge sweaty and urgently from a secret door in the corridor and do a legger.
Now, Schipol is a winner.
Love it there. Anytime I transit I feel happy.
Heathrow T-3 is the other winner.
It works so well. Really considers the traveller.
