Britain's Busiest Airport: Heathrow

With only one runway and two terminals open, Heathrow's depleted staff are fighting to keep business going. At the helm is King of Customer Service Demi, dishing out help to all those allowed to travel, including tracking down a missing passenger.

Flying for the last time out of Heathrow is the iconic Boeing 747, with plane spotters around the world hoping to bid it a fond farewell. Inside the terminal, it's hello to some new rather robotic members of staff.

Christmas is approaching and there's a new kid on the block: British airline, Domestic Carrier Eastern Airways. They're excited to be joining the big names at Heathrow, but one of their busiest flights is scuppered by yet more bad news.

Spring is about to be sprung and Heathrow is readying itself for a flurry of passengers.

Britain is on the cusp of holiday season and Heathrow is revving up for passengers from all over the globe. We meet a new member of the Passenger Experience Manager Team: Suki.

We go behind the scenes of the test and trace process. On the frontline is Joel, the manager of Heathrow's testing centre, who has to deal with an irate family.

With the new complicated regulations for travel, it's not surprising passengers are starting to fight back. The Aviation police enforce the new rules.

The airport may not be as busy as usual during the pandemic, but the aviation police are as busy as ever. An inbound passenger has armed officers waiting for him.

Staff at Heathrow prepare for the arrival of Air Force 1, and although the airport is quieter than usual, it is still a huge effort logistically to make sure things run smoothly. Meanwhile, security officer Estafania scrutinises the contents of passengers' hand luggage, as well as their face masks, and airside officer Ian has his hands full.

Terminal 3 re-opens its doors to the public 15 months into the global pandemic, with 11 Virgin flights set to take off, but teething problems threaten to delay one of the departures.
