With the Heathrow Hoppa bus only leaving the airport once an hour to go to our hotel, we decided to book in advance the meet and greet/airport transfer service provided by First Airport Taxis. Our flight was due to arrive at 6:20am. It was delayed by 15 minutes and so we fully expected our driver to be waiting for us in the arrivals hall. He was not. It took 3 phone calls to their head office and 2 responses from the driver before he turned up after we had been waiting for over 40 minutes. This is not the service for which we had paid £39. They have since reimbursed me the £8 meet and greet fee but that is not the point. If they cannot be relied upon to be there on time I will not use them again nor recommend them to any of my friends.
