BHX is no different to many other airports in charging a king's ransom to drop off and pick up
It kicked off after the Glasgow incident and there was no need for it. Just taking advantage of a situation to fill their pockets. May I remind you that before Glasgow, drop off and pick up was free of charge at all UK airports.
Btw, I wasn't suggesting that BHX was alone in this, but I have yet to come across an airport on my side of the channel which charges for this.
