The fourth season of a fly on the wall TV documentary on Heathrow is screened from tonight (Wednesday) by ITV.

The series ‘Heathrow: Britain’s Busiest Airport’ will run for six weeks

Filming took place over three months by a 14-strong crew to produce three hours of television, with much of the focus on Terminal 2.

A dedicated website provides a further glimpse behind the scenes at the London hub and the chance to win two return business class tickets to Malaysia with Malaysia Airlines.

Heathrow chief executive John Holland-Kaye said: “Returning for a fourth series, ‘Heathrow: Britain’s Busiest Airport’ is a project that encapsulates our dedicated network of colleagues who work around the clock to deliver a world-class airport service.

“The documentary gives millions of people a glimpse into the operations of one of the world’s busiest airports and I can tell you from experience, there is never a dull day.”
