Kuwait closed its airspace on 18 July 2026 following renewed Iranian missile and drone attacks, compelling Kuwait Airways to reschedule most flights rather than cancel them outright. The Directorate General of Civil Aviation imposed a precautionary closure of the OKAC FIR, prohibiting overflights and restricting arrivals and departures to prior-approved operations only. Kuwait Airways activated customer service channels and urged passengers to verify status via SMS or the airline app, confirming that rescheduling preserves ticket validity without full cancellation. This marks the only current FIR closure among Gulf states, creating immediate disruption for operators navigating the Persian Gulf while air defense systems intercepted multiple hostile targets. The restriction extends until at least 4 August 2026, with EASA advising operators to avoid the OKAC/Kuwait FIR at all altitudes under its current CZIB.
