Iran-US tensions triggered widespread flight cancellations at Islamabad International Airport on 3 June 2026, disrupting dozens of scheduled domestic and international services across multiple airlines.
Escalating military strikes between Iran and the US forced Gulf airspace into heightened alert, compelling airlines to avoid established routes over Iran and Iraq entirely.
Several major carriers suspended operations after facing severely limited routing alternatives, sharply elevated insurance costs, and mounting uncertainty over safe and viable flight corridors.
Pakistan International Airlines cancelled flights to Dubai, Kuala Lumpur, Karachi, Gilgit, and Quetta, with affected flight numbers including PK 211, PK 894, PK 603, PK 325, PK 369, and PK 319.
AirSial suspended its 2 scheduled Jeddah services, flights PF 728 and PF 718, as restricted airspace made operating those Gulf-bound routes operationally unfeasible under current regional conditions.
Airblue cancelled 3 international departures, including its Riyadh service PA 274, Abu Dhabi flight PA 230, and Jeddah-bound PA 272, all affecting late-night departure slots.
FlyJinnah suspended afternoon and evening services to Karachi and Quetta, while Kam Air cancelled its Kabul-bound flight RQ 928, further extending the disruption across regional aviation networks.
Aviation sources confirmed that ongoing airspace restrictions across Iran, Iraq, and parts of the Gulf are continuing to pressure flight planning across Pakistan’s entire international aviation network.
Airlines are increasingly rerouting away from high-risk corridors, though detour constraints and rising insurance costs are making numerous scheduled operations commercially and logistically unviable.
Passengers affected by the cancellations have been advised to maintain direct contact with their respective airlines, as flight schedules remain subject to further changes amid evolving regional developments.
