Prediction markets put the probability at 53%: Iran closes its airspace by June 30. Currently, markets are divided (53% YES, 47% NO). Middle East airspace restrictions result in more fuel burn and higher costs: Travel Weekly.
Iran's airspace status remained in flux through mid-May 2026, as a month-old ceasefire between Tehran and a US-led coalition showed signs of fraying. On May 10, Iran said it had formally replied to a US peace proposal — passed through Pakistan — even as drone strikes or airspace incursions were reported across the UAE, Kuwait, Qatar and Iraq. The US-owned cargo ship Neha was struck off the coast of Qatar by two Iranian drones the same day, according to Safesea Group chairman SV Anchan. Whether Iran closes its airspace formally before June 30 hinges largely on whether this fragile diplomatic track holds. [Guardian, May 10]
The economic cost of restricted overflights remained severe. The i6 Group estimates airlines paid up to an extra $3.9 billion on fuel in the first 60 days of the Iran war alone, circumventing closed corridors over Iranian, Iraqi and Israeli territory. Despite the persistent risk, Lufthansa Group carriers signalled cautious normalisation: Austrian Airlines will resume Tel Aviv service from the start of June, with Lufthansa, Swiss and Eurowings to follow. Operators continue to model contingency routes assuming Iran closes its airspace at short notice — a scenario that would again push Europe-Asia transit times up by several hours.

The structural factor for resolution is whether Tehran formalises a wartime closure before the June 30 deadline. Iranian officials have stated they are on "full readiness" to defend uranium stocks at nuclear sites, and Kuwait's detection of hostile drones in its airspace on May 10 underscores hawk warnings that the ceasefire is already eroding. Analysts caution that any breakdown in the US-Iran exchange could trigger a NOTAM-level closure within hours. Conversely, the carrier-led resumption of commercial flights to Tel Aviv from June 1 suggests operators are not currently pricing in a scenario where Iran closes its airspace on a sustained basis through Q2.
