I can cofirm Suzeman's response to a previous poster - the tunnels linking T2 to a future satellite were not constructed with the terminal and there are no current plans to build the satellite. As for capacity planning and spare capacity, MAN has the issue of being a 'Slot 1 -heavy' airport. Despite the decline from 22.5M to 17.5M pax, the overnight parking and early morning Slot 1 departures are still close to the 2006 peak levels, it is only after mid morning that the spare capacity really emerges. It has proved difficult to break this well-entrenched pattern of traffic, and so peak-hour capacity could very soon become an issue with any significant traffic growth. It's a conundrum for MAN, do you build more expensive capacity based upon Slot 1, or do you go all out to encourage more off-peak use, through charging mechanisms etc?.
