A unique booking reference is emailed to passengers after they complete a reservation and can be found on e-tickets and boarding passes. It enables travelers to manage their bookings and check in online. The code also gives travelers access to their flight details but not to PNR files with personal information.

A reservation reference, commonly known as a PNR (Passenger Name Record) or a Record Locator, is a unique 6-character alphanumeric code (e.g., XJ3K9L) assigned to a flight booking. In 2026, this code serves as the digital key to your entire travel itinerary. It is generated by the airline's Computer Reservation System (CRS) at the moment of booking and contains vital information including the passenger's name, flight numbers, seat assignments, meal preferences, and payment details. You can find this reference in your confirmation email, on your e-ticket, or at the bottom of your mobile boarding pass. The PNR is essential for managing your booking; you need it to check in online, change or cancel your flight, add extra baggage, or select a different seat. For security reasons, you should never share your PNR on social media, as anyone with this code and your last name can potentially access your personal information or even change your flight. It acts as the primary "ID" for your journey within the global aviation network, allowing different airlines and travel agencies to communicate and synchronize your travel data seamlessly.
