Florence Muls of Brussel Airport told the VRT that everything was alright until 8am, but after that the queues just got longer and longer.”
The company that runs Zaventem has called on passengers to check for any eventual changes to departure times and to leave home early. "An hour earlier than normal is certainly advisable”.
