Airlines operating across the Middle East are again reshaping schedules and reviewing routings after renewed US-Iran strikes disrupted flights across the Gulf, bringing fresh uncertainty to one of the world’s busiest international aviation corridors.

US forces struck Iranian military targets on 1 September, including air-defence, radar, maritime and communications facilities. Iran responded with missile and drone attacks targeting American interests in Bahrain, Kuwait, Jordan and Iraq. Bahrain said its air defences intercepted several attacks, while Kuwait reported a drone strike that caused a fire at a residential complex without injuries, according to Gulf News.

The escalation quickly spilled into commercial aviation. UAE passengers faced a patchwork of operating, delayed and cancelled services on 2 September, with airlines warning that schedules could change at short notice. Gulf News reported that Emirates cancelled its Dubai-Basra service, while Air Arabia scrapped several flights linking the UAE with Kuwait and Bahrain. Etihad reported delays and a diversion on other parts of its network, although services to Bahrain and Kuwait continued to operate.

For airlines, travel management companies and corporate buyers, the disruption is an unwelcome reversal. Carriers had been gradually rebuilding Middle East schedules after months of conflict-related cancellations and airspace restrictions. The latest escalation — including attacks affecting Bahrain and Kuwait — has put that recovery back under pressure.

Airspace risk returns to the centre of airline planning

The immediate concern is not simply whether airports remain open. Airlines must also contend with a shrinking pool of airspace considered suitable for commercial operations.

The European Union Aviation Safety Agency extended its Gulf conflict-zone warning to 30 September, with carriers continuing to adjust schedules and flight paths around regional risks. Gulf News reported that the warning comes as international carriers maintain suspensions on some Gulf routes. That matters well beyond the Gulf.

Dubai, Doha and Abu Dhabi are built around long-haul connecting traffic linking Europe with Asia, Africa and Australia. Even when an airport remains operational, avoiding higher-risk airspace can lengthen flight paths, increase fuel burn and complicate aircraft and crew rotations.

The consequences can spread quickly through a network. A longer inbound sector may delay the aircraft’s next departure; crews can run into duty-time limits; passengers miss onward connections. What starts as an airspace restriction hundreds of kilometres from an airport can become a timetable problem across several continents.

Gulf carriers face a different commercial calculation

Gulf airlines also have fewer options than foreign carriers when instability surrounds their home markets.

European and Asian airlines can suspend a Gulf route and redeploy aircraft elsewhere. Emirates, Etihad Airways, Qatar Airways and other regional operators have to preserve as much connectivity as safety conditions permit because their hubs sit at the centre of their business models.

The latest attacks reinforce that challenge. Iran launched missile and drone strikes targeting American interests in Bahrain, Kuwait and Jordan after the US strikes on Iran. Kuwait's air-defence systems responded to missile and drone threats, while emergency sirens were activated in Bahrain. For airlines, such rapidly changing security conditions make short-term network planning considerably harder.

The operating question is therefore becoming less binary. An airline may continue flying to a destination while changing its route, departure time or connection structure. For travel sellers, a flight showing as “operating” no longer tells the whole story.

TMCs have another layer of disruption to manage

Corporate travel managers and TMCs are once again having to build more resilience into Middle East itineraries. That means watching connection times, airline waiver policies and alternative gateways alongside basic flight status. Trips passing through Gulf hubs may require wider connection buffers, while companies sending staff into the region will need to reassess whether an itinerary remains workable if airspace restrictions tighten with little warning.

The commercial pressure is already visible. Dubai International Airport’s passenger traffic fell 31.3% in the first half of 2026 as the Iran war disrupted travel, Reuters reported, illustrating how prolonged instability can feed directly into traffic at one of the region’s largest aviation hubs.

The renewed fighting also raises another concern for airline economics: energy supply. The Strait of Hormuz remains central to global oil movements, and Gulf News reported that two attacks on commercial tankers had been recorded around the waterway in the previous 48 hours. Prolonged disruption to shipping could add another layer of cost pressure for carriers already dealing with longer routings.

For the travel trade, this phase of the crisis will be measured less by headline airport closures than by how long operational uncertainty persists. Airlines had started moving from emergency scheduling towards recovery. They are now back in a familiar position: protecting network integrity while planning around airspace that can change faster than the timetable.
