Gatwick Airport will be the "world's most efficient two-runway airport" if new designs are implemented, bosses claim. The Sussex airport has commissioned the designs from Sir Terry Farrell in a bid to eliminate queues and speed up aircraft turnaround times. The designs are part of the airport's campaign for a second runway. Passengers would be able to reach boarding gates within 30 minutes of arriving, the airport said. The designs show self-service bag drops and electronic security gates, and shorter taxiing times of seven minutes, reducing airline operating costs.
