Plane Addict;
The current terminal is capable of taking over 17 million passengers according to BHX, so no need for any expansion in the terminal for some time.
The next planned additions are a walkway pier at the back of the 70/80s in line with the railway track and a coulpe of fingers off eurohub with airbridges if required.
Thats from the airports latest future updates and appear on some recent drawings of the airport, who knows when/if they will be added
Also more moveable airbridges on the 40s which are rigid at present.
However the baggage reclaim surely needs more belts, and agree more staff required to man all the security points.
