I was flying to Schiphol on Monday and use that airport as my favorite for long-haul flights, even though I'm from Germany. It's a really nice airport.
This is when flying Air France/KLM within Europe. Maybe it's better in other terminals.
Changing between terminals at Heathrow is much less fun.
CDG I find confusing.
I decided to stay at a Heathrow airport hotel a while back. Turned out I had to change terminals and I'm pretty sure it took me at least as long as getting a shuttle bus to one of the hotels would have taken.
You often have to walk quite a ways too.
Overall though Heathrow is pretty good among the large European airports.
Worse than Frankfurt? It seems like the only food you can get there is a hot-dog...
It’s not as great as SIN, ICN or the once dominant HKG though.
