Basically anywhere past the security checks is okay, there are loads of windows which offer great views and three sections to the terminal A B and C. I departed from A area, which is where alot of the BAe 146 fleet seems to leave from and arrive in. It is possible to wander up and down the three areas and take photos and video, no one bothers you and the aircraft are close enough for good photography. It is also easy to watch runway action from inside the departures area.
