I agree with flower. Several years ago I diverted a 747 into Cardiff with 350 passengers. It was the most efficiently handled diversion that I have ever experienced. Within a few minutes of our arrival, seven coaches appeared outside the terminal building (I've no idea where they found them at that time of the morning) and in a very short time our passengers were heading for the M4. The crew were made very welcome at a local hostelry as LHR was out for most of the day. I gather that some of the later arrivals took a bit longer, but fortunately I'd decided to go to CWL when over Ireland so I guess we got first call on the coaches.
