A Very British Airline

This episode explores how the airline tries to persuade people to spend more to fly, revealing the world found behind the 'millionaire's door' at Heathrow Terminal 5 - a lounge, restaurant, spa and champagne bar reserved for those select few who are happy to part with small fortunes to fly in the airline's first class.

For 50 years London to New York has been the most glamorous and profitable route in BA's long-haul network. This was the route made famous by Concorde, and even today BA's JFK terminal caters for more of the rich and famous than anywhere else.

This looks at the heart of BA's New York operations to discover what it takes to keep the 28 flights a day running smoothly on this all-important route, even as the worst winter on record causes cancellations and delays.

In this final episode we're in the company's main control room with operations manager, and rugby enthusiast, Kevin McKenzie.

He reveals how the airline manages the challenges of operating out of the world's most congested airport, and deals with the knock-on effects of some passengers actions - from panic attacks before take-off to suspicious items discovered in luggage.
