Think that's expensive? About five years ago it cost us £95 to land a light twin engined helicopter at LHR.
It now costs £4500.
We don't even use the runway and have to give way to everything else. Sometimes we get held off, meaning we now also require a refuel.
The £1500 "extra security charge" brought in for the 2012 Olympics (so we were told) seems to have somehow been left in place.
