Did someone seriously mention FRA as a good airport? I admire your sense of masochism
In Europe I have still to find an airport that can beat CPH, Schiphol is the closest. Especially after the recent building frenzy, CPH has so much to offer a 2 hour layover goes like a breeze. Light, airy, easy to navigate, best shopping outside Dubai.
Middle east winner is clearly DXB, no contest what so ever.
Far East, Changi also a clear winner. But KUL is right behind, mainly since it's so empty
USA, hopeless. Ugly, worn down, dark, claustrophobic, impossible to navigate. Been through JFK, LAX and ORD; they all suck. Bit like Frankfurt really.
And for the best airline? Not yet invented I'm afraid. SAS is good, LH is good, SQ is good, EK is very good, BA can be good, AF is dodgy, KL can go either ways, DL stinks, AA is even worse, KE should be avoided at all cost ....
