I was very interested in the photos taken by Flybe about Brussels Airport in 2020 ( scale model - Brussels Expo- Vakantiesalon/Salon des vacances ).You can find these photos in the Coppermine Picture Gallery
When you have a good look , it seems (to me ) that the "Front park 2" will be replased by something new ( a new "refurbished Front park 2 , or ...? ).
You also can see a plane that is parked in front of the new Terminal 2; but I think it won't have many gates, or they have to build a new pier that is connected to it.
When I compare this scale model to today's airport, I can't see a new D -pier...
Although, in general very interesting to look at, and to find out more about it...
It would be nice if someone of the Brussels Airport Company could give some information...

Cheers!
