Hello,
This is the airport I am trying to create for my city, which I will post a project of later. The airport is one of the first parts of the new city, I have a 2-3 year old city on the same map far away(Actually really close, but this may be because of the huge airport), but still connected by road. I am building everything by myself, with the help of world edit. (The road, and the older parts of the old city are done without world edit. It is amazing how much work I put into it...)

As of right now, I have the security area complete, as well as parts of the main building.

There will 4 Terminals. A, B, C, D.

Terminals B and C will the main terminals, with A being smaller, and D being bigger (probably). Terminals A and D will go to the side. Unfortunately, the airport is larger than I thought, so Terminal A is going to be right next toon the other side of the highway.

When done, I hope this will be the largest most realistic airport in minecraft.

Completion: ~70%
