Brussels concentrates an institutional fabric that no other European city brings together in such a compact radius. The European Commission, the Council of the EU, the European Council, the Parliament (for its permanent committees and committee votes), the permanent representations of the 27 member states, and NATO headquarters (Evere, since 1967) together generate a permanent flow of diplomatic and ministerial flights, unparalleled in Europe.
This traffic has an operational profile distinct from tourism or even classic corporate travel: delegations with escorts, military state aircraft, VVIP flights with advance security coordination. ExecuJet Belgium holds IS-BAH Stage 2 accreditation (the most demanding ground safety standard in the industry); AviaVIP Brussels explicitly showcases expertise in head-of-state and military flights, with direct limousine access to the tarmac for delegations. This is the level of preparation that Brussels Airport FBOs have developed to meet the needs of this clientele.
Beyond institutional traffic, Brussels is also a dense business hub: European headquarters of pharmaceutical multinationals (UCB, IBA), consulting firms and sectoral federations (over 2,500 international organizations and lobbying groups registered), and financial services. The Brussels, Basel, and Frankfurt corridor generates regular round trips for teams of 4 to 8 people on midsize jets. This dual foundation, institutional and corporate, makes Brussels one of the rare European bizav markets where demand remains strong even outside summits and events.
