John Holland-Kaye, Chief Executive of Heathrow Airport, said:
“Our thoughts are with the victims of the terrible attacks in Brussels this morning and with our aviation colleagues at Zaventem Airport.
“We take the safety and security of our passengers and colleagues very seriously and in the light of events, we are working with the police at Heathrow who are providing a high visibility presence. We expect flights to Brussels Airport to be affected and ask passengers travelling there to check their flight status with their airline.”
