Just was looking at the map, and I noticed that Brasilia (bsb) can use some business bonus: It is the capital of brasil, and many people from congress and senate and other public functionaries do the weekly commute or even daily to get into the city. As for tourism, I think it's not really worth the visit, but other places nearby are rather interesting. I don't know if that warrants a tourism bonus?
Also for the Hercílio Luz International Airport(FLN): this one definitely should receive a tourist bonus! Great beaches around the island!
