the money you are talking about is indeed something important. LGG is a paradise for many freight companies because of the help of the walloon region goverment. The goal of the government is to create jobs, and it worked/works. 10.000 people are working in/for LGG. Subsidies are common in many place, no need to make a fuzz about it. It's a win-win situation and that's why i'm not affraid for the future of LGG and the future of all the people who get a job in the aviation industry there.
When TNT first came in LGG, it was only a small airport. Now it's the 6th biggest in Europe. Why would you leave that...
