A trip document generator, and nothing more
FlyProof turns the trip you type into a clean, printable document. It does not book anything.
Travel produces paperwork long after the booking is done: an expense claim that needs a flight receipt, a visa file that wants a legible itinerary, a group trip that needs one sheet everyone can read. FlyProof is a free generator for exactly that job. You type your own flights — route, dates, times, passengers — pick one of 13 formats, and export a PDF, PNG or JPG.
FlyProof builds the document, not the booking. It is not an airline, an agency or a booking channel, it holds no inventory, and it never mints a booking reference or PNR. Formats meant to stand in for a real reservation, such as the onward-travel proof sheet, are marked SPECIMEN on the document itself. If a checklist requires a genuine ticket or a real confirmed reservation, no generated document substitutes for it.
What we stand for
It never invents a booking
FlyProof builds the document, not the reservation. It is not connected to any airline and it never mints a booking reference or PNR — the documents say so on their face.
Computed, not guessed
Type a route and FlyProof works out the great-circle distance, block time and timezone-correct arrival for each leg from bundled open data. No flight API, so nothing to break and nothing to pay per document.
Yours to keep
No account, no email wall, no stored trip. You type your own trip details, pick a format, and export the file.
Where the flight data comes from
FlyProof has no live flight API. Every airport, airline and aircraft fact it needs is bundled into the app at build time from open datasets, which is why the generator works without a network call and costs nothing per document. Two projects make that possible, and this page is their credit:
- OurAirports — public domain. Airport names, IATA and ICAO codes, municipalities and coordinates.
- OpenFlights — Open Database License (ODbL). Airline names and codes, and the IANA timezone for each airport, which is what makes the computed arrival times correct rather than merely plausible.
Aircraft types and cruise speeds are curated from ICAO Doc 8643 designators and published manufacturer figures. Carrier and airport names appear as reference data only — they do not imply a partnership or an endorsement.
Entry requirements change by destination, nationality, visa class, airline and route. Read the current official wording first, and use a generated document only where a self-prepared itinerary is genuinely accepted.
