# Detect tampered and deepfake Onward Travel Proof > Onward travel proof is checked at a check-in desk more often than at a consulate, and it is checked because the airline pays to fly a refused passenger home. A booked departure from the destination country, dated inside the permitted stay, is what lets an agent board someone holding a one-way itinerary. The fakes run from 24-hour ticket rentals to reservation PDFs that were never filed with any carrier. TamperCheck examines the document for fields rewritten after it was issued. **Canonical URL:** https://tampercheck.ai/documents-support/onward_travel_proof **API document class:** `onward_travel_proof` --- ## What a genuine onward travel proof contains Onward travel proof is a reservation or ticket for departure from the destination country. It names the traveller exactly as the passport does, the booking reference, the carrier, the route with its departure airport and final destination, and the date and time of departure. Air, rail, bus and ferry bookings are each accepted in different places. Where the journey transits a Schengen airport, the proof also has to show the onward flight leaving the transit area, together with the visa or residence permit for the country at the end of it. The dates carry the burden here. Departure has to fall inside the visa-free allowance or the visa's validity, counted from the arrival date on the inbound ticket, and the traveller's name has to be identical across both documents. For airport transit, the two segments must connect within the same airport, with the second flight leaving from the international zone rather than requiring entry to the country. A ticket dated one day beyond the allowance defeats the entire reason for holding it. ## How onward travel proof forgeries are made ### Rented reservations Services hold a genuine reservation for 24 or 48 hours and email the confirmation, after which the hold expires. The PDF is real and the booking is not, so nothing in the file has been altered. What identifies it is the absence of a ticket number and a reference that no longer retrieves anything. ### Departure date pulled inside the allowance A real onward booking dated beyond the permitted stay is edited back inside it, so the traveller appears to be leaving in time. The change is two digits, and it frequently breaks the interval between the inbound arrival date and the departure printed on the same page. ### Route rewritten for transit The final destination or the transit airport is altered so a journey appears to stay airside. Airport codes are three characters and easy to swap, and a substituted code often contradicts the carrier's network and the flight number printed next to it. ### Carrier branding on a generic reservation A logo and colour bar are applied to a placeholder reservation so it reads as an airline confirmation. The branding sits at a resolution unlike the body text, and the layout matches nothing that carrier actually issues to passengers. ### Name substitution on a live booking Another passenger's active reservation is reissued under a new name, so the reference retrieves a genuine flight belonging to somebody else. The replaced name shifts the alignment of its line and usually disagrees with the name repeated in the contact or fare block. ### Reservations generated whole Confirmation PDFs produced by a generator, with a plausible reference, a real flight number and a fare breakdown that adds up. Consistency checks do not catch these. The rendering does, because a generated page carries different noise and font metrics from one a reservation system produced. ## What TamperCheck checks on an onward travel proof TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class. ### Date and validity consistency Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension. ### Reference and document number checks Document, account, and reference numbers are checked for issuer format conformance and against every other place the same value appears on the page. ### Field-level forensics Every text region is analysed in its own right rather than as part of one whole-page image. This catches the smoothed and feathered edits that whole-image Error Level Analysis misses entirely. ### And many more checks The three above are the layers that carry the most weight on an onward travel proof. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks. ## Who verifies an onward travel proof, and why Airlines and consulates assessing airport transit eligibility. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging. ## How to verify an onward travel proof in 4 steps 1. **Check the fields against each other.** Read routing and dates, passenger name, and booking reference together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original. 2. **Inspect the file metadata.** Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look. 3. **Ask for a second document.** Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare. 4. **Run a forensic check.** Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on an onward travel proof and returns a risk score from 0 to 100 in about a minute, at $0.50 per document. ## Frequently asked questions ### How do airlines verify onward travel proof? At the check-in desk, by retrieving the booking reference on their own systems or by reading the confirmation against the destination's entry rules. Airlines care because they bear the cost of returning a passenger who is refused entry, so the agent looks for a departure dated inside the permitted stay, in the same name as the passport, with a reference that actually resolves. ### Can an onward ticket be faked? Yes, and a rental industry exists around it, holding genuine reservations for 24 to 48 hours so the confirmation is real when it is shown and gone afterwards. Outright forgeries are common too: a departure date pulled inside the visa-free allowance, a route rewritten for transit, or a template dressed with a carrier logo. ### What counts as proof of onward travel? A booked departure from the destination country, dated within the permitted stay and in the traveller's own name. Flights are the usual form, but rail, bus and ferry bookings are accepted in many places, and a residence permit or onward visa is often required alongside where the journey transits Schengen airside. The requirement exists to catch one-way arrivals with no way out. ### How is onward travel proof different from a flight itinerary? It answers a different question: not how the trip is planned, but whether the traveller can leave before permission to stay expires. It is assessed by carriers and border officers rather than by a visa officer reading a whole file, and only three fields really count - the traveller's name, the departure date, and the destination beyond. ## Related document types - Invitation Letter: https://tampercheck.ai/documents-support/invitation_letter - Sponsor Letter: https://tampercheck.ai/documents-support/sponsor_letter - Travel Itinerary: https://tampercheck.ai/documents-support/travel_itinerary - Travel Agency Booking: https://tampercheck.ai/documents-support/travel_agency_booking - Accommodation Booking: https://tampercheck.ai/documents-support/accommodation_booking - Host Accommodation Form: https://tampercheck.ai/documents-support/host_accommodation_form --- Try TamperCheck now: https://tampercheck.ai/dashboard · Docs: https://tampercheck.ai/docs · Pricing: https://tampercheck.ai/pricing
