Heathrow's New Runway Won't Open Until 2039

Heathrow won't open its third runway by 2035 and now points to 2039, it told UK ministers. It still wants building approval by 2029, then up to ten years to finish. The UK's largest and busiest airport says its current runways have been packed, like a full parking lot, for over 20 years. Approval in 2029 decides if 2039 holds.
