I had to meet a friend coming in from Miami to Heathrow this morning.
Unfortunately, due to a mix up in the baggage reclaim it took over 1 hour 30 mins to return to the short stay car park. We were 5 minutes over the 90 mins band and the cost for that worked out at £8.00 for 95 minutes.
I do not know what the parking costs are for car parks in London, I guess a similarly high level, but I think the exorbitant costs of parking need to be investigated
Over to you Boris
