I have been through Amsterdam many times and know the airport well. My main comments today (2010) is that it is a fairly easy airport to use great shopping lots of airline lounges if you have time between connections and are a privileged member of a frequent flyer programme plenty of toilets / rest rooms some left luggage safes restaurants internet access etc. It has the advantage of not being as big as London Heathrow or some of the large USA airports (JFK or Chicago) and having lots of flights all over the place. I have used the Yotel (airport hotel where rooms are booked by the hour) and it is useful if you arrive late at night and leave the next morning. The airport has 2 main sections - international (Gates D - H) and EU (Gates B -D). Note that some of the D gates are in the international section and some in the EU section. The biggest problem with Amsterdam airport is if you are connecting between a EU flight and an international flight you might have quite a walk and will most likely (unless you are very lucky) have to wait in a ridiculous immigration queue to get from one section to the other. There is a separate queue behind each immigration officers desk so if you get stuck behind someone who is being questioned you could have quite a wait. They also never have enough immigration officers for the amount of passengers passing through here and so they have now started a first / business class separate queue. Basically this bit is a mess. Someone else's comment about security at the gates meaning you can't buy water after security is a good point. Just take an empty bottle and fill it on the plane. Also if you buy any liquids in any other airport make sure they seal it in a an approved EU plastic bag seal otherwise you will leave it behind in Amsterdam! Overall it is an easy airport to use. Pity about the immigration mess!
