Heathrow Delays Third Runway to 2039, Eyes 2029 Approval

Heathrow has told UK ministers its third runway will not open by 2035, pointing instead to 2039. It aims for planning permission — government approval to build — by 2029, then up to a decade to open. The UK's largest and busiest airport says its runways have run full for 20-plus years. The 2029 decision will decide if 2039 holds.
