Heathrow's CEO, Thomas Woldbye, aims for a final decision on a controversial third runway by the end of 2025, citing the need for increased capacity to support the U.K.'s economic growth. While discussions show positive momentum, the ultimate approval rests with the government amid ongoing environmental concerns and public opposition. The expansion plan includes a new runway and terminal, potentially adding 260,000 flights to the current cap of 480,000 annually.
