The U.S.–Israeli war on Iran has closed off a large aviation section in the Middle East, forcing airlines to reroute their flights. The conflict intensified after strikes targeted Iranian military and nuclear infrastructure, prompting Iran to respond with missile and drone attacks across the region.
As tensions grew, multiple governments began closing their airspace, forcing commercial airlines to quickly adjust routes.
Airspace is divided into zones known as Flight Information Regions, which are managed by national aviation authorities. In extreme situations such as war, governments issue a Notice to Air Missions to restrict or close their airspace.
Since the conflict began, several FIRs across the Middle East have been shut down, creating a gap across Iran, Iraq and parts of the Gulf.
The closure of these routes has forced airlines to avoid what aviation experts describe as a central corridor connecting Europe, Asia and Africa. According to aviation operations specialists, most flights are now being rerouted either north through the Caucasus region or south through Egypt, Saudi Arabia and Oman.
Airlines have prepared for scenarios like this for years.
Middle Eastern airspace has long been considered a geopolitical hotspot due to ongoing and past conflicts. As a result, many airlines already have contingency routes in place, allowing them to quickly adjust flight paths once restrictions were issued.
Even with contingency plans, the disruption has created congestion in alternative corridors and extended travel times for many flights.
For some travelers, the impact has been immediate.
Sauber Ali, a student from Queens, had plans to travel to Bangladesh to celebrate Eid with his grandmother. His parents had left several days earlier on Qatar Airways, but he delayed his trip because of academic commitments.
With the war affecting Middle Eastern airspace and Eid approaching on March 20, his options became limited.
“I normally would fly through the Middle East,” Ali said. “But now I only have the option to go through Asia.”
Instead of a 22-hour trip through the Gulf region, Ali must now consider routes crossing the Pacific with airlines such as Singapore Airlines, Cathay Pacific or Chinese carriers. These routes could take at least 31 hours with a minimum of three connections.
Ticket prices have also increased significantly. Ali estimated round-trip flights along these longer Pacific routes to cost between $2,200 and $3,000.
Airports across the region are also experiencing disruptions. Dubai International Airport, the world’s second busiest airport for international transit, has reduced operations, while Abu Dhabi’s Zayed International Airport has resumed only limited flights.
The U.S. Department of State has advised Americans in several Middle Eastern countries to depart immediately due to rising safety concerns.
According to officials, nearly 20,000 Americans have returned to the United States since the war began.
As the war continues, airlines, governments and travelers are all facing the consequences of a crisis that has effectively redrawn global flight paths overnight.
