Heathrow Airport has told investors it now expects just 83.6 million travellers to pass through its terminals in 2026—around 1.1 percent fewer than previously forecast—because the escalating war between Iran and Israel is suppressing demand for long-haul travel and forcing airlines to reroute or cancel services. In an investor update released on 26 June, Britain’s largest hub said uncertainty in the Gulf had already encouraged more passengers to connect through Heathrow instead of Middle-Eastern hubs, but overall long-haul demand was softening, particularly from corporate accounts with travel-risk thresholds. Lower traffic means Heathrow has cut its projected adjusted profit for the year by £147 million to £1.88 billion. While the airport handled 32.8 million passengers in the first five months—a 0.7 percent year-on-year rise—management cautioned that “continued volatility in the Middle East could dampen volumes over the remainder of the year.”
The downgrade will sharpen scrutiny of Heathrow’s £33 billion third-runway plan, whose economic benefit the Department for Transport recently estimated at only 0.05 percent of GDP—90 percent less than earlier studies. Heathrow insists the model understates trade, tourism and supply-chain gains and says engagement with the Civil Aviation Authority on expansion funding is “ongoing and constructive.”
For global-mobility managers, the forecast signals tighter seat availability and upward pressure on fares for Asia-Pacific and African itineraries routed via Heathrow this autumn. The airport’s mixed outlook also underlines how geopolitical flashpoints beyond Europe can quickly ripple through U.K. corporate travel budgets.

Amid this evolving travel landscape, organisations and individual travellers can turn to VisaHQ for real-time visa guidance, electronic applications and expedited passport renewals. The platform’s U.K. portal (https://www.visahq.com/united-kingdom/) consolidates the entry requirements for more than 200 destinations—an asset when airlines suddenly reroute via alternative hubs in Europe, Africa or Asia—helping mobility teams keep employees compliant and on schedule.
Travel buyers are advised to lock in Q4 long-haul bookings early, monitor airline re-routing surcharges (notably for flights skirting Iranian airspace) and review insurance war-risk exclusions. Organisations with Heathrow-centric mobility programmes should also keep an eye on the parallel debate over a third runway: slower expansion could constrain slot supply just as business travel rebounds in 2027–28.
In the shorter-term, travel duty-of-care teams should brief employees on possible Middle-East-related schedule changes, ensure traveller tracking systems capture amended routings, and build extra connection time into multi-sector itineraries that transit Heathrow.
