Worldwide Caution: Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation. Americans currently in the Middle East should exercise caution and heightened vigilance and should be prepared for flight cancellations, periodic airspace closures, and potential travel disruptions. Some airlines in the region have postponed resumption of earlier flight schedules; others have cancelled some routes.
