Houthis Warn Airlines to Halt Flights Through Saudi Airspace

A non-state actor declaring a sovereign airspace an "operational area" is a category of risk the insurance and overflight-fee markets have little practice pricing, and the Mecca and Medina carve-out suggests the warning is calibrated as much for political signalling as for military effect. The practical exposure sits with carriers whose long-haul routings depend on Saudi overflight, and with the Gulf hubs that aggregate that traffic. Whether Riyadh responds, and whether any airline actually reroutes, is the open question — the warning's force depends entirely on that second move, not on the statement itself.
