The delays at Brussels Airport are gradually being resolved, caused by adverse weather conditions (snow) and fog, severely reducing the airport capacity.
Passengers are advised to check the Brussels Airport departures website for further flight information.
Some flight delay this morning because of bad weather conditions in Europe. Check your flight on brusselsairport.be or the BRU airport app.

Of course I was a victim of these delays : my flight to Geneva departed 60 minutes late.
