Increased Airspace Restrictions Over Azerbaijan
The closure of airspace over the southern half of Azerbaijan is intensifying challenges for airlines as they adjust to disruptions caused by the ongoing conflict in the Gulf region.
Flight operations had already been significantly affected in an area that typically serves as a crucial hub for global aviation. However, a recent drone attack on Azerbaijan, a small Central Asian country, has forced many flights into a constrained corridor along the northern part of the country.
Limited Routing Options for Airlines
Aviation expert John Strickland highlighted the narrowing options available to airlines navigating the current airspace restrictions.
"There is now a very tight range of options for airlines trying to navigate the current situation," said Strickland.
Since the 2022 invasion of Ukraine, Western airlines have avoided Russian airspace, including Siberia. Currently, all flights are also steering clear of Iranian and Iraqi airspace, compelling carriers to seek alternative northern or southern routes.
Flight Congestion in Northern Azerbaijan
Real-time data from Flightradar24 illustrates significant congestion within an approximately 100-kilometer-wide corridor across northern Azerbaijan, a nation comparable in size to Portugal.
"It could mean delays and longer routings, just as happened post-Ukraine," Strickland explained.
"Flights already doing circuitous routing have even less choice."
In recent weeks, some airlines began adjusting their routes in response to escalating tensions in the Gulf. This week, a greater number of flights have been compelled to adopt routes further south to avoid the conflict zone.
Impact on Flight Scheduling and Airline Operations
Congestion is expected during peak periods, such as west-to-east flights in the afternoon and evening—when Europe-to-Asia flights are typically scheduled—and east-to-west flights early in the morning, coinciding with Asia-to-Europe schedules.
"That represented another big complication for airlines' planning on top of the usual factors, such as meteorological conditions, and the ramifications that a delayed flight can have for an aircraft and crew's next scheduled flight," Strickland noted.
Currently, most airlines are not required to add additional stops despite longer routes. However, Qantas has introduced a refueling stop in Singapore on its previously non-stop Perth-to-London service. Additionally, flights to India are generally experiencing longer durations, rerouted via southern paths around the Gulf.
