Inside Copenhagen Kastrup airport in april 2004.
Terminal 3 is the main terminal in 2009.
Terminal 2 is so interconnected with terminal 3 that you can consider it to be one terminal.
Terminal 1 is very small, as it's used for demestic flights, but Denmark is a very small country.
Terminal 2 is the old main terminal, before the construction of terminal 3. It's architecture is of an older style.
At terminal 2 you find the connexions to
the railway or the metro.
