The railway station, linked to the national and local rail network, as well as to the terminal via a monorail, featured an open air viewing area which overlooked the ends of runways 23L and 23R, as well as the taxiways linking them. As such it was a great place for photographing airliners both on the ground and in the air.
But sadly the viewing area is now closed, and it is reportedly a permanent closure.The other official viewing area, atop the terminal building, remains open. It is on top of concourse B, and reached via the third floor. There is a small entrance fee.
Opening times are now 10am-7pm year-round (no early summer opening now)
