I would like to tell you that you are doing a great job with both of the current sceneries. LSZH and KORD!.
Now, as I notice you are discussing in the future plans, I would like to guve my vote to MMMX, Mexico City Intl airport, witch is an excellent airport, with a lot of traffic, and with a very difficult approach over the city.
This hot and high airport offers direct flights to more than 100 destinations worldwide. In 2007, the airport served 25.9 million passengers. In optimal conditions, and with the current renovations and expansion projects completed, the airport will be able to handle up to 32 million passengers per year.
Here I let you some shots. Think about it, it would be great!http://www.jetphotos.net/viewphoto.php?id=5725210http://myaviation.net/?pid=00914876http://myaviation.net/?pid=00979813
