Overflight Permit

An overflight permit is government authorization for an aircraft to fly through a country's airspace without landing. International charter routings across Canada, the North Atlantic, Europe, and the Caribbean often require overflight permits filed by the operator before departure.

Why it matters

Why overflight permit matters

Permits are operator responsibilities, but passengers see them as invoice line items or scheduling constraints. Last-minute itinerary changes can delay permit approvals and push departure. Transatlantic and long Caribbean legs should name permit handling in the quote conversation.

Cost

How it affects cost

Permit fees and filing services may appear on international charter invoices. All-in quotes should define whether overflight and landing permit costs are bundled or passed through at cost.

Example

A quick example

A New York to Paris heavy-jet quote lists occupied hours plus a separate overflight and permit line covering routing through Canadian and European airspace. Comparing two transatlantic proposals requires those lines, not only hourly rate.

Common questions

Do passengers apply for overflight permits?

No. The Part 135 operator or their handling agent files permits. Passengers should confirm permits are included for the quoted routing before deposit.

Can permits delay my departure?

Yes. Routing or schedule changes close to departure can require new filings. Build buffer on international trips with tight connections.

Are overflight permits the same as landing permits?

No. Overflight covers en-route airspace. Landing permits and slot coordination apply at the destination country and airport separately.
