Heathrow airport charges the most IN THE WORLD for somewhere to put your car an unnamed source has said.
The London Evening Standard has published a story on their website showing that, as anyone who has been to the air-travel hub will suspect, finding somewhere to store your car while you tearfully/gleefully/nonchalantly wave goodbye/say hello to friends/loved ones/hated enemies/business superior/inferiors, is a massive urine-theft.
Heathrow does offer forward booking for parking spaces. The service is a must for business users, while the rest of us will continue to bore our relations with traffic anecdotes about the M25.
