- How long does an overflight permit take?
- It depends on the authority. Gulf states typically clear within 24 hours for a known operator, several African and Central Asian authorities need three to five working days, and a few require more for non-scheduled commercial traffic. LFS quotes the lead time per FIR when we screen the route.
- Can LFS get a same-day overflight permit?
- Often yes for AOG, medevac and humanitarian flights, where most authorities accept short-notice applications through their duty officer. We tell you honestly when an authority will not move, and dispatch plans an alternative routing instead.
- What happens if the flight is delayed?
- Most clearances are valid for a window either side of the filed entry time. Our controller monitors the slip and files a revision before the window expires, so the crew is not negotiating with a regulator from the cockpit.
- Do I need an overflight permit for an empty positioning flight?
- Usually yes. Most authorities treat a ferry or positioning sector as a non-scheduled flight requiring clearance, even without passengers on board.
How LFS handles it
Route screening
We take the planned route and list every FIR it crosses, the authority that owns each one, its lead time and whether your registry or nationality attracts extra scrutiny. If a FIR is closed, conflicted or priced badly, dispatch proposes a re-route before you commit.
Application
Each authority is filed in the format it accepts — AFTN, portal, email or agent — with the flight details, aircraft documents and, where required, purpose of flight. We file in parallel rather than in sequence so the slowest FIR sets the timeline, not the sum of them.
Approval numbers
Every clearance number is collected, checked against the filed callsign and route, and placed on the trip sheet the crew carries. Nothing is reported as approved until the number is in hand.
Validity watch
Permits issue with a window, not an open licence. The duty controller watches your estimated entry time against every window and files revisions before the aircraft is outside it.
- ·Certificate of registration and airworthiness
- ·Third-party liability insurance certificate showing the FIRs to be crossed
- ·Air Operator Certificate for commercial flights
- ·Crew list with licence and passport details
- ·Passenger manifest or 'no passengers' declaration
- ·Purpose-of-flight statement where the authority requires it
- ·Lead times run from a few hours in the Gulf to several working days in parts of Africa and Central Asia; we quote the real number per FIR, not an average.
- ·A change of registration, callsign or route usually voids the clearance and needs a fresh application, not an amendment.
- ·Weekend and public-holiday coverage differs by authority — we hold the duty contacts for the ones that matter on your routes.

Do I need an overflight permit for an empty positioning flight?
Usually yes. Most authorities treat a ferry or positioning sector as a non-scheduled flight requiring clearance, even without passengers on board.
Landing clearance is rarely just a form. Authorities ask who is handling the aircraft, where it will park, who the passengers are and why they are coming. LFS files the permit and the supporting arrangements together, so nothing is left half-approved.
OpenState aircraft are cleared through foreign ministries and defence channels, not the civil permit desk. LFS prepares the note verbale package, works the embassy channel and keeps the clearance current as the programme moves.
OpenAt a coordinated airport a permit alone will not get you in. LFS requests the arrival and departure slots, secures PPR and parking where it is scarce, and monitors both against your actual timings.
