Turkish airlines cancel Iran flights over US sanctions on Iranian aviation

What matters here is the spillover mechanism, not the route itself: US sanctions on Iranian aviation are now disrupting the operations of third-country carriers, turning compliance risk into a commercial cost for airlines with no direct exposure to the sanctions target. This affects Turkish carriers and their passengers, but also signals to other regional operators that serving Iran carries counterparty risk tied to Iranian aviation infrastructure. Whether more non-Iranian carriers follow, and whether the suspensions prove temporary or structural, is the open question worth watching.
