Overflight Permit

Definition

Authorization from a sovereign state allowing an aircraft to fly through its airspace without landing. Overflight permits are required for all international flights and must be obtained before departure — failure to secure a permit can result in the aircraft being denied entry, forcing a costly reroute. In Air Charter operations, overflight permits are a critical planning step, especially for routes crossing multiple countries (e.g., Shanghai to Frankfurt overflying Russia, Kazakhstan, and several EU states). FlashGL's charter team secures all required permits as part of the flight planning process.
