Skytrax has released its annual list of the world's best airports, based on surveys it distributed. Almost all of last year's winners are on the list again, and the only one in North America is Vancouver. But (IMHO) there's reason to question a list that includes Heathrow in the top 10!
There's also a list of the ten best terminals, and incredibly, Heathrow T5 is #1 on that list. Here are the lists.
Sparing us all my rant about Heathrow (unless you ask)...but have you noticed over the past few years the incredible increase in walking time from check-in to gate in many airports? Half a mile is not unusual anymore, and some of the airports that made the list (Schiphol, Madrid Barajas) are among the bad examples.
