What Information Is Stored in a PNR?

A Passenger Name Record can contain much more than a passenger name and flight number.

Depending on the reservation, a PNR can include:

• record locator;
• passenger name;
• travel dates;
• itinerary;
• contact details;
• travel agency information;
• booking status;
• ticketing information;
• seat information;
• baggage information;
• code-share information;
• payment-related information;
• special service information.

But not every PNR contains every possible field.

ICAO treats PNR as commercial reservation data

ICAO explains that PNR is data collected in airline reservation and related systems as part of normal commercial operations.

Some reservations are information-rich.

Others can contain only a smaller set such as:

• name;
• itinerary;
• contact information;
• ticket indicator.

That is why two PNRs can look very different.

Common PNR data elements

Current international PNR standards include fields such as:

PNR record locator

The code used to identify the record.

Reservation / ticket issue date

Records when the reservation was created and, where applicable, when ticketing occurred.

Intended travel dates

The planned journey dates.

Passenger name

The person or people associated with the reservation.

Contact information

Phone, email and other contact data where provided.

Complete travel itinerary

The flight segments stored in the booking.

Travel agency information

The agency or agent associated with the booking where relevant.

Travel status

Can include confirmation and check-in status.

Ticketing information

Can include:

• ticket number;
• ticket issuance date;
• ticketing field data.

Seat and baggage information

Can include seat assignments and baggage information where available.

Codeshare data

Relevant when the itinerary involves partner airlines.

Historical changes

Some PNR data standards also contemplate booking-history information.

Does every PNR contain passport details?

No.

Passport and API data can be collected and associated with the journey, but not every booking contains the same identity information at the time the reservation is first created.

Many passengers book a flight before entering passport details.

So the absence of a passport number does not by itself mean no reservation exists.

Does every PNR contain payment data?

No.

PNR standards allow payment and billing information where available, but that does not mean every reservation has the same payment fields.

A temporary unticketed reservation can exist before final payment/ticketing.

The PNR is a reservation record, not simply a payment receipt.

Does every PNR contain a ticket number?

No.

This is the key distinction.

Ticketing information can be part of the PNR after ticket issuance.

But a PNR can exist before the ticket number exists.

That is why an unticketed reservation can have:

• passenger;
• itinerary;
• booking reference;

without an e-ticket number.

What does a PNR not prove?

A PNR by itself does not automatically prove:

• full payment;
• ticket issuance;
• boarding eligibility;
• visa approval;
• immigration admission;
• permanent reservation status.

Those questions require other evidence.

Why governments care about PNR data

PNR is also used in border-security and law-enforcement frameworks.

ICAO has standards governing how states collect, process and protect passenger reservation data.

That regulatory use is separate from the traveler-facing purpose of using a booking reference to retrieve a reservation.

What should travelers care about?

For normal booking verification, the useful fields are usually:

• correct passenger name;
• correct itinerary;
• active booking reference;
• travel date;
• airline;
• ticket number if ticketing matters.

You generally do not need to understand every backend PNR data element just to verify a temporary reservation.

Privacy point

Because PNR can contain personal and travel information, do not post your full booking reference, itinerary and surname publicly.

Those details can be enough to expose trip information on some airline websites.

Treat a PNR like travel-account information, not like a public tracking code.

Bottom line

A PNR can contain a large set of booking, passenger, itinerary, ticketing and service information.

But the fields vary by reservation.

Most importantly, a PNR can exist before a ticket number is issued, so the presence of a PNR does not automatically prove that the flight has been paid and ticketed.
