Quick question about the Chauffeur service in the UK. I'm flying in to Manchester, which states that the service is available within 70 miles of the airport. I've done some reading around to see whether this is as the crow flies or road distance and not found a definitive answer. Does anyone know which is correct? (I live < 70 miles from the airport as the crow flies, but > 90 miles from the airport by the fastest route)...
