Heathrow Issues Warning Over Ongoing Middle East Disruption

London Heathrow has warned of an unpredictable period ahead as the Middle East conflict triggers a dramatic slump in passenger numbers and reshapes global flight patterns.

The UK's largest and busiest airport reported that passenger traffic on its Middle Eastern routes fell by more than 51 per cent in March 2026 compared with the same month the previous year, one of the sharpest single-route declines the airport has recorded in recent memory. Despite this, Heathrow's overall figures remained in positive territory, with the airport welcoming 6.6 million passengers in total during March, up nearly 7 per cent year-on-year, as demand shifted to other parts of its long-haul network.

The sharp drop in Middle East travel has been directly linked to the escalation of conflict involving Iran, following a joint military offensive by the United States and Israel. The hostilities prompted airspace closures across parts of the Persian Gulf — one of the world's most heavily used corridors for long-haul aviation — and raised serious safety concerns among travellers and airlines operating in the region.

As a result, many passengers have chosen to avoid routing their journeys through the Middle East altogether, disrupting established flight paths that have for decades connected Europe, Asia, Africa, and beyond.​​​​​​​

Heathrow CEO Thomas Woldbye acknowledged the challenge directly, stating: "We're doing everything we can to support airlines and passengers as travel trends shift during the Middle East crisis. While Heathrow's long-haul network absorbed demand in March, the outlook for the next few months remains uncertain."

The airport recorded a 10 per cent spike in transfer passengers in March, as travellers sought to reroute through London rather than connect via hubs in the Gulf. However, officials were quick to note this boost may be temporary, as Heathrow's two runways are currently operating at full capacity — limiting the airport's ability to scale up further to meet surging rerouted demand.​​​​​​​

Heathrow has confirmed that its day-to-day operations remain unaffected, and that supply chain impacts — including jet fuel availability — have not disrupted the airport's functioning to date. The airport says it is monitoring the situation closely and working with the UK Government and airline partners to protect passengers' journeys.

That said, travellers with plans involving the Middle East — whether as a destination or as a connecting hub — should expect continued uncertainty in the months ahead. Flight schedules remain subject to change at short notice, and airlines are actively reassessing their regional operations.​​​​​​​
