Heathrow presses for third runway as airlines and British Airways weigh expansion costs, while Birmingham plans £2bn growth
Heathrow chief executive Thomas Woldbye says more than 40 airlines are seeking slots and warns investors cannot wait indefinitely for approval of a third runway, whose cost estimates range from £33 billion to £49 billion. British Airways wants government investment to contain costs; Birmingham Airport’s draft £2 billion plan targets 30 million passengers a year within 15 years.
