Middle East crisis leads to 10% spike in Heathrow passengers – but there’s a catch
London’s Heathrow Airport recorded a notable uptick in passenger numbers last month as travellers and airlines rerouted around airspace closures in the Middle East, but the airport warned that its longer-term growth remains constrained and the outlook is uncertain.
In March 2026, Heathrow handled 6.645 million terminal passengers, a 6.9% increase from the same month a year earlier.
The airport attributed part of the rise to a 10% spike in transfer passengers, as flights were diverted away from affected Middle Eastern airspace amid ongoing regional conflict.
Heathrow CEO Thomas Woldbye said the hub was doing everything possible to support airlines and passengers as travel patterns shifted. “While Heathrow’s long-haul network absorbed demand in March, the outlook for the next few months remains uncertain,” he said.
Sharp drop in Middle East routes
The gains were not uniform as direct traffic to and from the Middle East plummeted 51.1% to just 294,000 passengers in March, while air transport movements on those routes fell 47.4%. Cargo from the region was also hit hard, down 54.3%.
Instead, demand shifted to other long-haul markets. Asia/Pacific traffic surged 31.1% to 1.116 million passengers, Africa rose 23.3%, and North America grew 6.8%. EU traffic was up 11.6%. Overall for the first three months of 2026, Heathrow served 18.925 million passengers, up 3.7% year-on-year.
The airport noted that it has temporarily absorbed demand displaced from elsewhere, but emphasised a key limitation. Its runway slots are effectively full, meaning growth continues to lag behind some EU competitors that have more capacity to expand.
Heathrow said knock-on effects from the crisis, including potential supply chain issues around fuel, have not impacted its day-to-day operations so far. The airport said it is closely monitoring the situation and working with the UK government and airlines to safeguard passenger journeys.
Passenger experience also held up well despite the volatility. In March’s Skytrax World Airport Awards, travelers voted Heathrow the world’s best airport for shopping, third-best for security screening, and the hub climbed five places in the overall rankings.
The traffic figures came as Heathrow marked the 80th anniversary of its first flight on March 25. On that day in 1946, a Lancastrian aircraft named Starlight departed for Buenos Aires. Since opening, the airport has welcomed more than 2.9 billion passengers and supported nearly £300 billion in British trade last year alone.
For the 12 months through March 2026, Heathrow handled 85.141 million passengers, up 1.9% on the prior year. However, with the Middle East situation fluid, the airport stopped short of providing a firm forecast for the busy summer period ahead.
