The European Union Aviation Safety Agency has advised airlines to avoid several Gulf airspaces after renewed United States strikes on Iran raised the risk of missile attacks, drone activity and the accidental targeting of civilian aircraft.The strengthened warning covers Bahrain, Kuwait, Qatar, the United Arab Emirates and the Gulf of Oman. It is scheduled to remain valid until July 29, although the agency could revise or extend the guidance if military activity continues. Separate advisories urging operators to avoid Iran, Iraq and Lebanon remain in force until August 31.
The decision reverses an easing of regional precautions announced after a temporary reduction in hostilities. EASA had allowed a wider Middle East bulletin to expire on July 8 while retaining country-specific warnings for airspace considered especially vulnerable to military operations.
Fresh exchanges between Washington and Tehran prompted the agency to reassess the threat. United States forces have carried out further attacks on Iranian military and coastal targets, while Iran has launched missiles and drones towards bases used by American forces across the Gulf and neighbouring states.
Major United States military installations in Bahrain, Kuwait, Qatar and the UAE increase the possibility of retaliatory attacks close to heavily used commercial aviation corridors. The Gulf of Oman is also considered vulnerable because aircraft crossing it may operate near military vessels, surveillance platforms and weapons systems deployed around the Strait of Hormuz.
EASA warned that civilian aircraft could face danger from surface-to-air missiles, ballistic weapons, drones, interception operations and military misidentification. The risk may persist even when airports and national airspaces remain formally open, because missile trajectories and defensive responses can cross international flight paths within minutes.
European airlines are not legally required to treat every EASA conflict-zone bulletin as an absolute prohibition. National regulators and individual operators retain responsibility for deciding whether a route can be flown safely. Carriers usually combine the agency’s guidance with intelligence assessments, government restrictions, insurance requirements and real-time operational information.
Several airlines have already diverted services away from sensitive sections of the region or adjusted departure times to reduce exposure. Others continue to serve Gulf hubs while using modified routes and additional fuel reserves. Passengers may face longer journeys, delayed connections and cancellations as operators respond to short-notice changes.
Dubai, Abu Dhabi, Doha and Bahrain are among the world’s most important international transit centres. Disruption around them can quickly affect journeys between Europe, Asia, Africa and Australasia. Avoiding Gulf corridors can force aircraft towards routes over Egypt and Saudi Arabia or north through Central Asia and the Caucasus.
Diversions increase fuel consumption and crew costs while reducing the number of passengers or cargo an aircraft can carry. They may also create congestion in narrower corridors that remain available. Flight planners must account for extra distance, changing weather conditions, airport curfews and the availability of diversion airports.
Kuwaiti airspace has faced tighter operational limitations than some neighbouring flight information regions, while parts of Iranian airspace remain restricted. Iraq may be technically available for selected operations, but EASA continues to classify it as unsuitable because of the possibility of military escalation and unpredictable weapons activity.
Navigation interference presents an additional hazard. Pilots operating around the eastern Mediterranean and Gulf have reported episodes of satellite-positioning disruption, including jamming and spoofing. Such interference can display incorrect aircraft positions, affect navigation systems and increase workloads for flight crews and air traffic controllers.
Airlines generally retain conventional navigation procedures and ground-based guidance as safeguards. Strong interference can nevertheless complicate approaches, diversions and operations through crowded airspace, particularly when combined with military activity and fast-changing route restrictions.
The aviation warning comes as tension also spreads towards Yemen and Saudi Arabia. Houthi forces have launched missiles and drones towards Abha airport and warned airlines about Saudi airspace following attacks on Sana’a airport. No casualties were reported at Abha, but the exchange has raised concern that another front could reopen alongside the confrontation involving Iran and the United States.
Airlines are expected to maintain flexible schedules and review routes before each departure. Travellers connecting through Gulf airports have been advised to verify flight times directly with carriers, as an open airport does not guarantee that every airline will operate its published service.
