On the eve of Bulgarian accession to European Union, Sofia Airport celebrated its 70th anniversary with a new appearance – 27 December 2006 marked the opening of Terminal 2. With annual capacity of 2.6 million passengers, Terminal 2 was designed to allow for a future extension to meet the requirements of the fast developing traffic during the next decade. Indeed, in December 2013 Terminal 2 was extended to the north, which increased its passenger capacity with about 200 000 per year.

The central building of Terminal 2 rests on a total area of 56 850 m², its pier stretching out to 242 m with 7 passenger boarding bridges and bus exits. The access to the eight levels of the terminal building is facilitated by 12 elevators and 7 escalators. A passageway connects the halls to the 800-space parking garage.
