The UK's Gatwick Airport has unveiled a new low-risk, two-runway plan, designed by architect Sir Terry Farrell.
The new designs incorporate various improvements to eliminate queues with self-service bag drops and electronic security gates that will enable passengers to reach boarding gates just 30min after arriving at the airport.
Passengers can connect with flights leaving from different terminals in just 45min, and connection times from the same terminal at Gatwick will be just 30min. According to the new plans, push back to take off will be just seven minutes, compared with 45min at the three-runway Heathrow Airport.
Gatwick claims that the expansion will allow it to become the world's most efficient two-runway airport.
Both runways will operate in mixed mode, which means both will have arriving and departing flights. A new runway is expected to be operational by 2025.
Gatwick Airport CEO Stewart Wingate said: "An expanded Gatwick can be delivered quickly and at no additional cost to the taxpayer so the UK can reap the economic benefits of expansion sooner.
"Our plan recognises that traditional methods of transferring are in decline with many passengers exploiting new options to 'self-connect' between a mix of low-cost, short and medium-haul, charter and long-haul flights, depending on their budget and needs."
Sir Terry Farrell said: "Queues have literally been designed out and the new terminal will be simple and convenient to use with few changes of level.
"The airfield itself would also offer the shortest taxiing distances possible with the new apron sitting between, and in close-proximity to, both the existing and new runways."
