Emirates President Sir Tim Clark has urged the UK government to renationalise Heathrow Airport to break the deadlock over its £33 billion third runway project. Clark argues that public ownership would enable the government to align investors and airlines on funding and delivery, avoiding reliance on higher airline charges. He contrasts Heathrow’s costly expansion model with Dubai’s more efficient five-runway facility, noting current capacity of 85 million passengers could rise to 160 million annually. Renationalisation remains Clark’s proposal, not official policy, yet it signals a potential shift in how operators and regulators approach long-haul hub capacity planning.
