Brussels Airlines serve Brussels from many destinations worldwide.
Brussels' main airport is Brussels International Airport- previously known as Zaventem (IATA code BRU). From the airport, a train (€5.05) runs every 15 mins to Brussels Nord, with the journey taking 15 minutes. There is also a bus (numbers 12 and 21) (€3, or €4 on board) every 20 to 30 minutes via Rondpoint Schumann to the Place de Luxembourg district, from where the same ticket is valid for another 30 minutes on the metro or busses into the centre. A taxi to the centre costs around €25 when booked in advance, otherwise around €35. Taxis bleus: +32 (0)2 268 0000, Taxi Brussels: +32 (0)2 411 4142, Taxis verts: +32 (0)2 349 4949. Beware of hidden charges, Taxis verts may quote you one price over the phone, but they charge an additional € 25 plus parking if your flight is delayed. Always confirm the final charge with your driver before getting in the car. If you've just arrived at the airport's train station, first check the time of the next train then go up one level and check whether a bus 12 or 21 is about to depart and take whichever is quicker depending on your final destination. For fix-rate taxi and minibus services visit [3]. They can take you anywhere in Belgium, not only Brussels.
There are several budget airlines, including Ryanair and Wizzair, who fly to Charleroi airport. This airport is south of Brussels (IATA code CRL) and one hour away from Brussels Midi Station at the city centre by shuttle bus (€ 13 one way, €22 return), or by train to Charleroi Sud station and then by TEC Bus A (€2.50 one way) direct from Station to the airport. You can also get a taxi from the airport to the city centre, but this will cost a fixed price of approximately €90. The best deal is to book a shared airport transfer at www.charleroitransfer.com [6], the only door to door minibus company at Charleroi Airport (price for groups start from €10).
Brussels airport has a luggage locker service (Floor 0) where one can leave their luggage for a fixed duration. The lockers say that you will have to retrieve your luggage within 72 hours or else they will be taken out. But they will actually be moved to the room adjacent and stored there until you retrieve them. This is a useful facility for people wanting to stow away big suitcases somewhere safe. The rate is €7.50 per day.
Antwerp airport (IATA code ANR) also has a good train connection to Brussels.
Brussels has three main train stations: Bruxelles Midi-Brussel Zuid, to the south of the city core, Bruxelles Central-Brussel Centraal, which is right next to the city centre, and Bruxelles Nord-Brussel Noord, to the north of the city center (at Place Rogier). Unfortunately, high-speed trains stop only at Midi/Zuid, so you need to take the tram (or an ordinary train) a few stops north to get to Grand Place.
