Iran War Sparks Global Aviation Chaos — Airlines Face Massive Disruptions

The Iran War Isn’t Just Disrupting Oil. It’s Grounding the World’s Busiest Air Hub

Dubai International handled 95 million international passengers in 2025. It is the busiest international airport on the planet. Emirates and Qatar Airways are the world’s two largest long-haul carriers by available seat-kilometres. Between them, the Gulf’s aviation infrastructure forms the spine of global international air travel — the engine room through which hundreds of millions of passengers transit each year between Europe, Asia, Africa and the Americas.

The Iran war has brought that engine room to a near standstill.

The Super-Connector Model Under Threat

The Gulf carriers built their dominance on a deceptively simple proposition: place a hub in the middle of the world, connect every major city to every other major city through it, and offer a product good enough to make passengers choose the longer route. For Emirates, Etihad and Qatar Airways, that model transformed Dubai and Doha from regional outposts into the most strategically important aviation nodes on earth.

It also created a single point of failure.

When conflict erupted and airspace across the region became compromised, the consequences cascaded globally within hours. According to aviation data firm Cirium, two-fifths of approximately 3,800 scheduled flights into the Gulf region were cancelled on a single day in early March. Thousands of passengers were stranded — not only in Dubai, Doha and Abu Dhabi, but in cities across Europe, Asia and Africa where onward connections had already been missed.

Those outside the Gulf could at least explore rerouting options. Those already in the region largely could not.

Which Airlines Are Affected — and How

The disruption has spread well beyond the Gulf carriers themselves.

Emirates — the world’s largest international airline — suspended the majority of its operations at the height of the disruption before reinstating a limited schedule. Its network of over 140 destinations means any sustained grounding creates a ripple effect across dozens of partner carriers and codeshare routes globally.

Etihad Airways, Abu Dhabi’s flag carrier, followed a similar pattern of suspension and partial reinstatement, with particular impact on routes connecting South Asia, East Africa and Australia — corridors where it holds dominant market share.

Qatar Airways, operating out of Doha — geographically adjacent to the conflict zone — has faced severe restrictions on its normal flight paths, forcing significant rerouting and schedule disruptions across its network. Doha’s Hamad International Airport, which handled over 50 million passengers in 2025, has seen dramatically reduced throughput.

The disruption extends well beyond Gulf operators. Lufthansa, British Airways, Air France and KLM have all suspended or severely curtailed routes through Gulf airspace, forcing passengers onto longer alternative routings at significantly higher cost. Indian carriers including Air India and IndiGo — among the heaviest users of Gulf transit routes — have been forced to reroute flights south over the Arabian Sea, adding hours to journeys and creating substantial fuel cost overruns.

Even flights to neighbouring countries have not been spared. Routes into Saudi Arabia, Jordan and Egypt have all been hit, reflecting how broadly the regional airspace disruption has spread beyond the immediate conflict zone.

The Financial Toll

For the airlines most exposed, the financial consequences are severe. Emirates alone generates revenues exceeding $30bn annually, with the overwhelming majority tied to its long-haul transit model. Every day of significant disruption represents tens of millions of dollars in lost revenue, compensation costs and stranded aircraft repositioning expenses.

The oil price shock triggered by the Iran war compounds the problem. Jet fuel, which typically accounts for 20-25 per cent of airline operating costs, has surged in line with crude prices — hitting carriers with a simultaneous demand destruction and cost inflation shock that analysts describe as a worst-case scenario.

When Does Normal Resume?

With Trump signalling the war may be approaching its conclusion and oil prices retreating sharply from their peak, cautious optimism has returned to aviation markets. Emirates and Etihad’s partial reinstatement of services suggests operational confidence is slowly rebuilding.

But the Gulf carriers’ super-connector model was built on the assumption of stable, open airspace as a permanent condition. The Iran war has demonstrated — in the most disruptive way possible — that it is not.
