Why is the Eurowings Airbus A320neo flight from Dubai now taking 11 hours?

Commercial aviation across the Middle East is facing major disruption. Airlines are implementing extended flight times and fuel stops due to geopolitical tensions. The core issue is the decision by many carriers to avoid Iranian airspace. This safety precaution is forcing significant, hours-long diversions on key East-West routes.

Regulatory Guidance and Safety Concerns

The European Union Aviation Safety Agency (EASA) issued a formal warning. This Conflict Zone Information Bulletin (CZIB) was released on January 16, 2026. It formally recommended that air operators avoid the Tehran Flight Information Region (FIR) entirely. The advisory cites a "high risk to civil flights" at all altitudes. This risk stems from the potential for civilian aircraft misidentification. Regional tensions have placed Iranian air defense forces on a heightened state of alert. The EASA bulletin remains in force through mid-February 2026.

The Eurowings Diversion: A Case Study

An extreme example of the operational impact is a recent Eurowings Airbus A320neo diversion. Eurowings flight EW1153 from Dubai International Airport (DXB) to Stuttgart Airport (STR) was severely affected. The flight was forced to adopt a much longer route to comply with the directive to avoid Iranian airspace.

Double Diversion and Delays

The narrow-body Airbus A320neo aircraft lacked the range for the extended flight times and fuel stops. The original seven-hour flight first diverted to Thessaloniki Airport (SKG), Greece, for a technical refuelling stop. This stop added significant time to the journey. By the time the aircraft was ready to continue, a nighttime landing curfew was in effect at its destination, Stuttgart. This curfew forced a second diversion to Nuremberg Airport (NUE), which lacks overnight restrictions. The cumulative effect was an 11-hour delay for passengers.

Wider Industry and Operational Impact

Other carriers are facing similar challenges due to the Middle East airspace restrictions. The Lufthansa Group, which owns Eurowings, has directed its airlines to avoid Iranian and Iraqi airspace.

• Low-Cost Carriers: Budget airlines like Wizz Air are also making technical stops in Cyprus or Greece for long-haul westbound flights from the Gulf. Their single-aisle fleets are particularly susceptible to range limitations.
• Asian Carriers: India's largest airline, IndiGo, suspended some Central Asia routes. The airline cited the longer diversions as not operationally viable for its Airbus A321neo fleet.
• Gulf Carriers: Major players like Emirates and Qatar Airways are rerouting around the Tehran FIR. This adds between 30 and 90 minutes to some flight times.

These diversions directly increase airline operational costs through greater increased fuel burn and crew duty limits. For airlines, the decision is a balance between safety and financial viability. The heightened geopolitical risk commercial aviation faces in the region continues to reshape global air traffic corridors.
