Brussels International Airport is one of the busiest in Western Europe, catering to incoming and outgoing flights of different countries and cities. Delhi too has frequent flights landing in this airport. From the airport, one can make their way to the city centre by SNCB train or by car in less than half an hour.

By Air: There is no nonstop Delhi to Brussels flight, which means whichever flight you book will be having stopovers somewhere between India and Belgium. Stopovers on the way to Brussels are usually at the neighbouring EU cities or sometimes at Middle-Eastern cities. The best Delhi to Brussels flight duration is served by Finnair via Helsinki and KLM via Amsterdam at a little more than 11 hours. Swiss Air and Lufthansa are close behind.

By Road: There are cities with bus service to Brussels, but there are no such from Delhi. Paris and London have the best buses to Brussels.

By Rail: From Delhi there are is direct railway network connection with Brussels. But there are quite a few from the neighbouring cities. Among many, the best is the high-speed Eurostar TGV train across the English Channel to Brussels.
