Heathrow is set to reveal plans to move the position of its proposed third runway.
The airport is to make its final submission to the Howard Davies-led Airports Commission this week.
This will include calls to investigate placing a congestion charge on passengers travelling to the runway, as well as plans for above-market-rate compensation for 750 homes that would need to be bought.
It will also show that the position for the airport’s proposed third runway has moved closer to the A4 to avoid the need for major works where the M25 meets the M4.
The Airports Commission concluded in December there was need for an additional runway to be operational in the South East by 2030. It shortlisted three options for this - a second landing strip at Gatwick; and two proposals for a third runway at Heathrow.
