In terms of location, Prestwick airport would have to be in Shawlands to be comparable to Bremen.
My point regarding the terminal was that PIK is never going to be successful for passenger ops if they keep throwing money at the existing terminal. With a small easy to maintain and heat terminal, much lower staffing overheads - e.g. the check-in agents, passenger assistants, dispatchers all multi-task. In other small airports such as Knock, Waterford, etc the check-in staff become the gate agents and then dispatch the aircraft as the passengers move through the terminal, thereby optimising the utilisation of staff. While its not meant to offend anyone, a lot of staff at PIK seem to spend a large amount of their days bored (their words!) and not doing very much. Perhaps the harshness of this winter will force a change.
