London’s Heathrow Sees Passenger Dip as Middle East Conflict Dampens Travel Demand

London’s Heathrow Airport reported a 5% drop in passenger numbers last month, with 6.7 million travelers passing through in April compared to the same period in 2025. The airport attributed the decline to the ongoing conflict in the Middle East, which has prompted “short-term adjustments to travel plans” among international flyers. War between the US and Israel against Iran has caused widespread flight cancellations, delays, and longer journey times, weighing on demand for overseas trips.

Despite the overall dip, the number of transfer passengers—those connecting through Heathrow to onward flights—rose 10% year-on-year in April. Travelers rerouting to Asia and Oceania increasingly chose Heathrow over rival Gulf hubs like Dubai and Doha, reflecting shifting flight patterns amid the crisis.

The conflict has also raised fears of fuel shortages this summer. The effective blockade of the Strait of Hormuz, a channel used by more than a fifth of the world’s oil, has driven jet fuel prices to roughly $181 a barrel—double the average from last year. Heathrow CEO Thomas Woldbye said travel demand “remains strong” and current fuel supplies are stable, but the airport plans to review its 2026 passenger forecast next month.

Airlines are bracing for higher costs. British Airways’ owner said last week it would try to recover most of a €2 billion fuel cost hit through “revenue and cost management actions,” likely pushing fares higher. However, some carriers have begun cutting prices on summer flights to encourage bookings. According to Financial Times analysis, fares for week-long July trips dropped on 27 of the top 50 European routes to the Mediterranean between early April and early May.
