Avoiding drop off charges at Manchester Airport
I only discovered this recently and it may apply to all airports and potentially to pick-up as well.
If you are a blue badge holder or the driver dropping you off is then show it to the duty attendant when you are dropped off and get him/her to radio to security with the registration number of the vehicle and they should be allowed to leave without paying the punitive £5 fee. This also applies to taxis as well.
