Used EDI for a city break on the continent. The approach roads which don't appear to have changed much in 20 years and the front of terminal area must be one of the worst in Europe for an airport this size. A complete shambles when the airport is busy. Does nobody in BAA ever look at airports in Europe and see what can be achieved? Immigration area is another mess three aircraft arrive at the same time and the queues are out onto the apron. Why not expand this area and why no "Fast Track"? I notice that one of new traffic lights at the A8 roundabout has cunningly hidden the sign for Edinburgh and the Bypass. This doesn't help tourists trying to handle roundabouts and find their way out of the airport.
