Changes this year: Houston, Charlotte, Warsaw and Philly have all shuffled off the top 100, making room for Mauritius, LAX, Geneva and Bogota. Bogota jumped an impressive 160 places to get it's current spot; must have had some serious renovations. Other reorderings were mostly minor, except for Istanbul Ataturk which took a nosedive.
What a big jump towards the top for CDG. Some years ago, I made an oath to never ever use this airport anymore, it was such a disgrace, thinking about how people may feel when they were confronted to that pathetic first sight of my country. I'm really glad they care on the issue, I hope it's really that much improved.
If you start naming cities with bad and/or no major airports, then you won't do very well. I guess it would help a lot if you travel constantly like I do. Barring that I would go for big, international cities with a reputation for developing their infrastructure. Even then you would miss some, though.
oh man is that what the color for Middle East looks like on most monitors? Hideous. It's supposed to be a dark olive green... but I know the laptop I was using before had a problem displaying colors correctly especially yellows.
