Passenger numbers at Heathrow Airport fell sharply in April as the conflict in the Middle East disrupted international travel patterns and pushed many travellers to avoid traditional Gulf transit hubs.
Britain’s busiest airport said 6.7 million passengers travelled through Heathrow in April 2026, down 5.3% compared with the same month last year. The decline marked Heathrow’s biggest annual monthly fall since March 2025.
The airport blamed the slowdown on “the ongoing impact of the Middle East conflict on some markets and short-term adjustments to travel plans”. The latest figures come as airlines and airports across Europe continue to deal with route disruptions, higher fuel prices and uncertainty linked to tensions involving Iran, Israel and the wider Gulf region.
Thomas Woldbye, Chief Executive of Heathrow, said demand for travel remained resilient despite the disruption.
“While we have seen some short-term disruption linked to the Middle East conflict, demand for travel remains strong with current fuel supplies stable,” he said.
Woldbye added that April was still Heathrow’s busiest month of the year so far, underlining the airport’s role as a major global hub during periods of uncertainty.
The sharpest decline came on routes linked to the Middle East. Heathrow said passenger traffic to the region dropped by more than 50% year on year as travellers changed itineraries and some airlines reduced operations because of security concerns and airspace restrictions.
The conflict has severely affected aviation networks across the Gulf, a region that normally acts as one of the world’s most important connecting corridors between Europe, Asia and Australia.
Major hub airports including Dubai International Airport, Hamad International Airport in Doha and Abu Dhabi International Airport usually handle hundreds of thousands of transit passengers each day. However, ongoing instability has encouraged some travellers to reroute via European hubs such as Heathrow instead.
As a result, Heathrow reported a 10% rise in transfer passengers in April. Many travellers flying between Europe and destinations in Asia or Oceania chose to connect through London rather than transit through Gulf airports.
The airport said the rerouting trend highlighted Heathrow’s importance as a flexible international hub capable of adapting quickly to changing geopolitical conditions.
Despite the overall decline in passenger traffic, several regions showed continued growth. Passenger numbers to Asia-Pacific destinations increased by 5.6%, while Africa recorded growth of 6.8%. Transatlantic traffic to North America slipped slightly by around 1.3%, while European routes remained broadly stable.
Heathrow also reported that aircraft movements fell 4.6% year on year in April to around 38,500 flights. Flights linked to the Middle East recorded some of the steepest declines.
The wider aviation industry remains concerned about the impact of the conflict on fuel supplies and airline costs. The closure and disruption of shipping routes around the Strait of Hormuz have raised fears over jet fuel availability and higher operating costs during the peak summer season.
According to aviation industry data, jet fuel prices recently climbed to around $181 per barrel, roughly double the average level seen last year.
Airlines have already begun adjusting schedules and reassessing capacity for summer travel. Some carriers are warning of rising ticket prices due to higher fuel costs, while others have started discounting fares on selected European leisure routes to protect bookings.
International Airlines Group, the parent company of British Airways, recently warned that higher fuel costs could add billions of euros to expenses this year, increasing pressure across the sector.
Heathrow said it would review and update its passenger forecast for 2026 in June because of the uncertain geopolitical outlook.
Earlier this year, the airport had forecast around 85 million passengers for 2026. Heathrow handled a record 84.5 million passengers in 2025 and remains one of Europe’s busiest international airports.
The airport also continues to push for long-term expansion plans, including its proposed third runway project, which Heathrow argues is necessary to maintain Britain’s competitiveness as a global aviation hub.
Woldbye said Heathrow was working closely with airlines and the UK government ahead of the summer holiday season to help provide certainty for passengers.
“We know passengers want certainty when planning their hard-earned summer holidays, so we are supporting government and airlines as they work through their plans to get passengers on their journeys,” he said.
The latest figures highlight how quickly global aviation demand can shift during geopolitical crises. While conflict in the Middle East has disrupted some traditional long-haul travel flows, Heathrow’s role as a major European transfer hub appears to be helping offset part of the impact.
