More than 30 people died in the March 22 terrorist attacks, in which suicide bombers blew themselves up in the airport departure hall and at the city’s Maelbeek underground railway station.
The repair work in the departure hall is still ongoing, but passengers are now able to access 111 check-in counters while 36 check-in counters will remain operational in temporary structures that were put up after the attacks.
On Sunday afternoon, about 400 passengers used the reopened departure hall to check in for flights to Malaga, Lisbon and Palma de Mallorca, the airport said in a statement.
Its passenger capacity is expected to return to full by mid-June.
