DUBAI — Airlines operating routes through Middle Eastern airspace are quietly recalibrating long-term network strategies as military tensions across the region show no clear path toward resolution, raising the prospect of permanent changes to global aviation routing, insurance pricing and hub-and-spoke economics that have underpinned the industry for two decades, according to aviation executives, insurers and air traffic control officials interviewed over the past two weeks.
The immediate operational picture has stabilised after a period of acute disruption in late 2025, when airspace closures over portions of the Gulf forced carriers to reroute dozens of daily flights around restricted zones, adding between 90 minutes and three hours to some journeys and costing the industry an estimated $2.4 billion in additional fuel and crew expenses over a six-week period, according to the aviation data firm Aerotrack Intelligence.
Those closures have largely reopened, but carriers and their insurers are no longer treating the episode as an isolated event. War-risk premiums for routes operating within proximity of conflict zones have risen between 180 and 340 percent depending on the corridor, according to Lloyd’s of London market sources. Several underwriters have placed explicit exclusion clauses in policies covering specific geographic boxes that did not exist two years ago.
“What changed is the risk modelling,” said James Edbury, head of aviation risk at broking firm Halcyon Maritime and Air. “We used to treat Middle East disruption as a discrete, bounded incident — something like a NOTAM that lasts a few days. Now the modelling has to treat it as a persistent, multi-year environmental condition. That changes everything from premium structure to fleet deployment decisions.”
The three largest Gulf-based carriers — whose names this report withholds to focus on industry-wide dynamics rather than individual competitive positions — collectively operate roughly 1,400 daily departures and carry approximately 18 percent of global long-haul passenger traffic through hub airports positioned to exploit the region’s geographic centrality between Europe, Africa and Asia. Their business model depends on overflight rights and airspace stability across a band of territory that is now structurally less predictable.
Alternative routing corridors are emerging. Traffic between Europe and South and Southeast Asia via the Indian Ocean and Arabian Sea has increased by roughly 12 percent compared with pre-2024 baselines, while some carriers have reinstated routes through Central Asian corridors that had fallen out of commercial use following the suspension of Russian overflights in 2022. Each alternative adds cost and complexity: the Indian Ocean routing adds approximately 45 minutes to London-Singapore services; Central Asian corridors require fuel stops that major long-haul widebodies were not originally configured to need.
Airport planners in secondary hub cities — including Nairobi, Colombo and Almaty — are studying whether the disruption creates durable traffic-capture opportunities. “The hub geography of aviation is not fixed. It shifted once when Gulf carriers emerged and it can shift again,” said Priya Kandaiah, director of aviation development at an international airport consultancy based in Singapore. “The question is whether the disruption is prolonged enough and severe enough to change airline network planning at a 10-year horizon.”
Passengers are so far absorbing the effects without significant outward disruption, partly because the rerouting has been managed without widespread cancellations. But travel managers at multinational corporations report that booking lead times for Middle East-routed itineraries have lengthened and that corporate travel policies at several large companies now require approval for routings through the highest-risk corridors.
Regulators at the International Civil Aviation Organization convened an extraordinary working group in February to assess airspace management protocols and liability frameworks for carrier losses attributable to geopolitical closure. A preliminary report is expected in August. Industry observers say the body is unlikely to produce binding guidance quickly, leaving airlines and insurers to negotiate risk allocation bilaterally in the interim.
The longer-term scenario that concerns analysts most is not acute crisis but chronic uncertainty — a situation in which airspace risk never fully resolves but also never triggers a decisive restructuring, forcing carriers to absorb elevated costs indefinitely while making capital allocation decisions under persistent ambiguity. “The aviation industry can adapt to almost anything given time,” said Edbury. “The worst case is not a catastrophe. The worst case is a prolonged grey zone where nobody quite knows how to price the risk.”
