Iran appeared to reopen its airspace on Thursday after a sudden overnight closure disrupted flights across the region, even as airlines largely continued to avoid the country amid heightened security warnings and ongoing regional tensions.
The overnight closure lasted around five hours after a Notice to Air Missions, or NOTAM, was issued, according to the aviation risk-monitoring site Safe Airspace.
Safe Airspace warns that the main danger for civil aircraft in Iranian airspace is misidentification by air defense systems during heightened tensions, rating the overall risk level currently as “One — Do Not Fly.”

President Donald Trump told reporters in the Oval Office on Wednesday that he was informed the killing of protesters in Iran was “stopping.”
“We have been notified and really strongly, but we’ll find out what that all means. But, we’ve been told that the killing in Iran is stopping,” he said.
Sen. Lindsey Graham, R-S.C., disagreed with Trump, writing on X that every indication he’s seen shows that the Iranian regime’s killing of anti-government protesters is “still very much in full swing.”
“The death toll is mounting by the hour. Hoping that help is on the way,” he wrote.
