Have you read my post?
Allow vehicles into the drop off area free of charge and charge if their stay extends say beyond 15 minutes. The area at BHX is large enough and the traffic will flow even better than it does now! Tell me, how do major airports such as Schiphol, Dusseldorf, Brussels continue to allow terminal drop off without any congestion? I know the answer but I'll let you work it out. If you're defending the need to charge for a simple drop off then you must be working in airport management.
Edit: Sorry, I should say UK airport management!
