Major hubs including Dubai, Doha and Abu Dhabi have faced operational constraints, leaving passengers unable to travel as planned while airlines adjust routes, suspend services and redeploy capacity to other regions.

Carriers across Europe, North America and Asia have suspended flights to destinations such as Tel Aviv, Beirut, Riyadh and Dubai, with some cancellations extending into the summer and autumn travel seasons. Several airlines are also avoiding the airspace of conflict-affected countries, including Iran, Iraq, Syria and Israel, increasing flight times and operational costs.

Emirates said it is operating a reduced schedule while continuing to serve more than 100 destinations, while Etihad Airways reported maintaining flights from Abu Dhabi to around 80 destinations under adjusted operations.European carriers including Air France and KLM have suspended multiple Middle East routes, while Lufthansa and affiliated airlines extended cancellations to a wide range of destinations until late October.

Low-cost and regional carriers have similarly scaled back operations, citing safety concerns and logistical constraints.In North America, Delta Air Lines has delayed the resumption of key routes to Tel Aviv, and Air Canada has extended cancellations to both Tel Aviv and Dubai through early September.

Asian airlines, including Cathay Pacific and Japan Airlines, have also suspended services to Gulf destinations while adding capacity on European routes to meet shifting demand.Meanwhile, some carriers are reallocating resources to less-affected markets.

Airlines such as Qantas and others are increasing flights to European cities, responding to a surge in passenger demand away from disrupted Middle Eastern corridors.Industry participants say the disruptions are being compounded by rising jet fuel costs and shortages linked to constrained oil supplies, forcing airlines to balance safety, cost pressures and demand volatility.

With uncertainty persisting over the duration of the conflict, airlines continue to revise schedules, with many warning that disruptions could extend for months as geopolitical tensions reshape global aviation patterns.

Major transit centers including Dubai, Doha and Abu Dhabi have faced closures or limited operations, leaving thousands of passengers stranded and prompting carriers to adjust schedules deep into the summer and, in some cases, later in the year.

The disruption has affected both passenger and cargo operations, with airlines citing safety concerns and restricted airspace.European carriers have taken some of the most extensive measures.

The Lufthansa Group has suspended flights to multiple destinations including Dubai, Tel Aviv and Tehran until at least late May, with several routes halted through October. Air France-KLM has similarly paused services to key regional cities, while Finnair continues to avoid airspace over Iran, Iraq, Syria and Israel.

North American carriers have also scaled back operations. Delta Air Lines has cancelled its New York–Tel Aviv route and delayed the restart of other Israel-bound services, while Air Canada has suspended flights to Tel Aviv and Dubai until September.

Middle Eastern airlines are operating under constrained conditions. Emirates reported a reduced flight schedule following partial reopening of regional airspace, while Etihad Airways said it continues to operate a limited network from Abu Dhabi.Asian carriers have also adjusted capacity.

Cathay Pacific has cancelled flights to Dubai and Riyadh until June while adding capacity to European destinations to meet shifting demand. Singapore Airlines extended its Dubai suspension through May and increased flights to London and Melbourne.

Several low-cost and regional carriers, including Wizz Air and Pegasus Airlines, have halted services to multiple Middle Eastern destinations, reflecting the broad impact across the aviation sector.

Airlines have also begun reallocating capacity to Europe, Africa and parts of Asia, where demand has surged as passengers reroute travel plans away from the conflict zone. Some carriers, including Qantas, have increased frequencies on European routes to accommodate displaced demand.

The evolving situation has created uncertainty for airlines and travelers alike, with many carriers indicating that further schedule adjustments will depend on security conditions and airspace availability in the coming weeks.
