Berlin Brandenburg is the flagship new gateway for the city, and the country, and is due to open in late June.
It is being built adjoining the existing Schonefeld Airport, which will close down along with Tegel Airport, meaning all air traffic will use one modern hub.
In some reassuring news for spotters, provision is being made for an observation deck atop the terminal giving views across the airport and runways, and no doubt offering great opportunities for photography, plus an elevated viewing tower with additional views.
This should come as no surprise, as Germany is one of the most spotter-friendly countries, with most airports providing some kind of viewing area.
Berlin Brandenburg is set to become quite a busy airport, not only because it is combining the operators of two airports into one, but because many airlines are opening new routes, and national carrier Lufthansa has announced a proper hub at the airport, with worldwide routes.
The observation deck will be located on Level 4 of the terminal, and will be semi-covered, with telescopes. Opening times will be 6am-10pm in the summer, and 8am-8pm in the winter.
It is also planned to offer airside bus tours that will take you to the maintenance areas and fire station.
In addition to the observation deck, a viewing tower called the Infotower will be provided with elevated views over the airfield. This will be open from 10am-6pm.
