Heathrow Airport was hit by the Iran war: passenger traffic fell by 5% in April, and passenger traffic in the Middle East plummeted by more than 50%

Passenger traffic at London’s Heathrow Airport fell sharply in April as the ongoing conflict with Iran disrupted global aviation networks.Britain’s busiest airport said some 6.7 million passengers passed through its terminals this month, down 5% from the same period last year, Reuters reported.Traffic related to the Middle East has been hardest hit, down more than 50%, as airlines grapple with airspace closures, cancellations and longer routes during the regional crisis. Heathrow said the drop reflected “short-term adjustments to travel plans” caused by geopolitical tensions.

Transit traffic increases as flyers reroute via London

Despite the overall slowdown, the number of connecting passengers at Heathrow increased by 10%, with many passengers diverted to London to connect to Asia and Oceania. The airport has benefited from passengers avoiding major Gulf transport hubs such as Dubai and Doha due to disruption in the area.Airport officials noted that while the conflict continues to impact international aviation, Heathrow has absorbed some displaced travel demand.

Fuel crisis worries add to pressure on airlines

The conflict also heightened concerns about aviation fuel supplies due to disruptions to tanker traffic in the Strait of Hormuz, a key global oil shipping route.Jet fuel prices have nearly doubled from last year’s levels, according to industry data, raising concerns about higher ticket prices and possible fuel shortages during the peak summer season.Last week, British Airways parent IAG said it may try to offset sharp rises in fuel costs through higher fares and other cost management measures. Meanwhile, some airlines are reportedly cutting fares on some European summer routes to avoid a drop in bookings.

Heathrow Airport to review 2026 forecasts

Heathrow chief executive Thomas Woldbye described the situation as “short-term disruption” and insisted underlying travel demand remained strong despite the volatility. He added that April remains Heathrow’s busiest month so far this year.However, the airport said it would reassess and update passenger forecasts for 2026 next month as conflict and uncertainty about the global travel outlook persist.
