Thomas Woldbye says part of airport’s problem is UK passengers walk on the left while others walk on the right

Heathrow airport has revealed a crowding problem that a third runway cannot solve: British and foreign travellers walk on different sides, and keep colliding, according to its chief executive.

Thomas Woldbye said that while Heathrow serviced more passengers in a smaller overall area than comparable European hubs, part of the London airport’s trouble was the differing continental sense of direction.
