Country procedures, lead times and CAA contacts.

Saudi Arabia overflight: same-day in most cases, twenty-four hours for short-notice landings outside major hubs. Iran overflight: minimum forty-eight hours, longer for non-friendly state-of-registry. Iraq overflight: twenty-four to forty-eight hours via the Baghdad FIR; Erbil-specific approvals are separate. Egypt overflight and landing: same-day to seventy-two hours depending on whether the leg touches a military-controlled FIR boundary.

Each of these has corner cases: state-aircraft markers on the flight plan, dual-use cargo, prior-permission requirements at specific airports, and operator-blacklist screening that runs silently in the background. The dispatch sheet shows the lead time we are working to, not the optimistic figure the regulator publishes.

Every permit application carries the operator's AOC reference, the aircraft registration, the route with FIRs in sequence, the planned entry and exit times in UTC, and any cargo or passenger sensitivities the regulator asks about. We file via the regulator's primary channel and a documented backup channel — usually a named officer at the CAA — so a portal outage does not stall the trip.

When a permit is denied we want the reason in writing before the next move. The most common denials are AOC-state political, dual-use cargo flags and incorrect aircraft category. Each has a different recovery path; we run the recovery rather than re-applying blindly.

Saudi GACA has tightened state-of-registry screening since 2024 but the practical lead time for friendly operators is still inside same-day. Iran's CAO is consistent on the forty-eight-hour rule and has a working backup channel for medical and humanitarian flights. Iraq's MoT is reliable inside twenty-four hours via the Baghdad FIR but airports in the Kurdish region require a separate approval that operators sometimes miss.

We maintain a rolling note on each of these regulators so a change in posture — and there are several per quarter — is reflected in our quoted lead time within a day, not a quarter.

Diplomatic clearance routes through the originating state's foreign ministry and the receiving state's diplomatic clearance unit, not the CAA. Lead times are longer (typically five working days) and the format of the request is prescribed. State-aircraft markers on the flight plan must match the diplomatic clearance number exactly or the receiving FIR will refuse entry at the boundary.

Head-of-state movements add a presidential or royal protocol layer on top. For these we work with the operator's diplomatic liaison and the receiving protocol office in parallel — the air-navigation permit is necessary but not sufficient.

Most permits issue with a validity window of a few hours either side of the planned entry. A delayed departure can push the aircraft outside the window and the permit will not stretch; an amendment must be filed. We watch the time-to-window and file the amendment before the captain has to ask.

Revocation is rare but real. When the political picture changes between filing and execution the regulator can pull the permit in minutes. The dispatch sheet keeps the alternate routing live so a revocation triggers a pre-planned diversion plan rather than a scramble.
