In the early 1990s, a new 7-storey terminal building joined the existing terminal, along with a 3-storey "Pier B" and a series of access bridges and roads. 20 metres below ground, a complete rail station was built to facilitate connections with the high-speed train network. In the process, BESIX built a 300-metre rail tunnel under the road infrastructure and another 400-metre tunnel beneath the runways, between the passenger terminal and the future Pier A.
At the start of the 2000s, BESIX built the new "Pier A" with three floors and 31 boarding gates, and connected to another new 5-storey infrastructure, also built by BESIX. Pier A is divided into 3 parts: a technical corridor, a luggage corridor and a public corridor with three passenger conveyor belts and 10 lifts.
Passengers and visitors can take in the friendly skies even before boarding, thanks to three panoramic lifts that add to the airport's ten ordinary lifts.
