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.

The incident, involving an Air Canada jet and a fire truck at around 11:37 p.m. local time, killed both pilots and has intensified concerns over staffing shortages and operational pressures within U.S. air traffic control.

According to a LaGuardia Tower standard operating procedures document, local air control and ground control roles should not be combined before midnight or within 90 minutes of a shift starting.

The rule was introduced following a 1997 ground collision at the airport and remained in force as of 2026.

Preliminary information suggests that, on the night of the crash, one controller may have been handling both runway operations and ground traffic, a practice inconsistent with those procedures.

The National Transportation Safety Board said it is examining the duties performed by controllers at the time, though it has not confirmed whether roles were combined.

NTSB Chair Jennifer Homendy said two controllers were working in the tower: one overseeing active runways and another acting as controller-in-charge while issuing departure clearances.

However, it remains unclear who was responsible for ground traffic management.Audio recordings reviewed by multiple current and former controllers suggest the runway controller may also have been handling ground movements, though this has not been officially confirmed.

Data showed 70 commercial flights operated at LaGuardia between 10 p.m. and the time of the crash, significantly above the average of 53 for that period in recent years, increasing workload complexity.

Controllers cited by Reuters said such traffic levels would typically require additional staffing rather than consolidation of roles. The Federal Aviation Administration, which oversees air traffic control, did not respond to requests for comment.

Investigators have emphasized that aviation accidents generally result from multiple contributing factors rather than a single cause, with the inquiry into the collision ongoing.
