London's Heathrow Airport experienced a sharp decline in passenger traffic in April, with the ongoing Iran conflict leading to disruptions across global aviation networks. The UK's busiest airport said around 6.7 million passengers traveled through its terminals during the month, a 5 percent decline compared to the same period last year, according to Reuters.
Middle East Routes Hit Hard
Traffic linked to the Middle East took the biggest hit, plunging by more than 50 percent as airlines grappled with airspace closures, cancellations, and longer flight routes amid the regional crisis. Heathrow said the fall reflected short-term adjustments to travel plans caused by geopolitical tensions.
Transit Traffic Rises
Despite the overall slowdown, Heathrow saw a 10 percent jump in transfer passengers, with many travelers rerouting through London for onward flights to Asia and Oceania. The airport benefited as passengers avoided major Gulf transit hubs such as Dubai and Doha due to disruptions in the region. Airport officials noted that Heathrow has absorbed some displaced travel demand, even as the conflict continues to impact international aviation.
Fuel Crisis Fears Add Pressure
The conflict has also intensified concerns over jet fuel supplies after disruptions in tanker movement through the Strait of Hormuz, a crucial global oil shipping route. According to industry data, jet fuel prices have nearly doubled from last year's levels, raising fears of higher airfares and possible fuel shortages during the peak summer season. Last week, British Airways owner IAG indicated it may try to offset a massive rise in fuel costs through fare hikes and other cost-management measures. At the same time, some airlines are reportedly cutting ticket prices on select European summer routes to avoid weaker bookings.
Heathrow to Review 2026 Forecast
Heathrow Chief Executive Thomas Woldbye described the situation as a short-term disruption, insisting that underlying travel demand remains strong despite the volatility. He added that April was still Heathrow's busiest month so far this year. However, the airport said it will reassess and update its passenger forecast for 2026 next month as uncertainty over the conflict and global travel outlook persists.
