Heathrow Airport has announced several improvements and revisions to its initial expansion proposal released in July last year.
Under the new plan, the airport will have the capacity to add 40 new direct daily routes to emerging economic destinations such as San Jose, Wuhan and Kolkata.
The airport has also added several other propositions including a third runway to be delivered by 2025.
Additionally, a new Heathrow West and Heathrow East layout would create two points of entry to reduce bottlenecks and delays on the ground.
By 2030, the airport proposes to reduce the number of people in Heathrow's noise footprint by at least 30 per cent. The overall goal is to deliver the lowest noise levels since the 1970s.
The airport estimates that 12,000 fewer people would be affected by the noise level if the new runway were built further south. There are also considerations to create a single transit system to bring connection times up to speed with those offered by other major airports.
The new submission was developed after extensive consultation with local residents businesses, passengers, airlines and regional representatives.
"Only Heathrow will connect all of the UK to fast growing international markets. The plans we are submitting to the Airports Commission demonstrate major economic benefits from a third runway for the whole of the UK," Development Director of Heathrow John Holland-Kaye said.
