When you book a flight, two separate things happen in airline systems: a reservation is created, and then a ticket is issued against it once the fare is paid. For a visa application, the difference matters.
The reservation (PNR)
A reservation is a record of who is flying, on which flights, on which dates. It's identified by a short booking reference, usually six letters and numbers, often called a PNR (Passenger Name Record). A reservation can exist before payment — that's how travel agents hold seats while a customer decides.
Unpaid reservations don't last forever. The airline or booking system sets a time limit, after which an unpaid reservation is released. That limit varies by airline and fare.
The ticket (e-ticket number)
A ticket is issued when the fare is paid. It has its own number — typically 13 digits — separate from the booking reference. The ticket is what entitles you to check in and board.
Side by side
| Reservation | Paid ticket | |
|---|---|---|
| Identifier | Booking reference / PNR | E-ticket number (plus the PNR) |
| Paid fare? | No | Yes |
| Lets you board? | No | Yes |
| Expires? | Yes, if not ticketed in time | Valid for the booked flights |
| Cost to you | Low service fee | Full fare, often non-refundable |
Which one does a visa application need?
That depends on the country, so check the official checklist for your application. Some examples from official sources (checked 6 October 2026):
- The European Commission's Schengen page asks for supporting documents on purpose of stay, financial means, accommodation and intention to return — it doesn't require a paid ticket. See our Schengen guide.
- GOV.UK lists flight bookings (unless transiting) as "less useful as evidence" for UK visitor visas. See our UK guide.
- IRCC gives "flight details" as an example of evidence for a Canada visitor visa. See our Canada guide.
In each case, buying the full fare before you have a decision puts money at risk if the visa is refused or delayed.
Important limits
A reservation is not a ticket, and you should never present it as one. Don't use it to try to board, and don't alter any document. If an officer asks whether you've bought a ticket, the honest answer is that you've reserved the itinerary and will buy the ticket once the visa is granted.
