A Finnair booking reference (also known as a PNR or Record Locator) is a unique six-character code consisting of a combination of letters and numbers (excluding 0 and 1 to avoid confusion with O and I). You can find this code in your confirmation email, on your e-ticket, or on your boarding pass. It is the essential "key" to managing your trip; you will need it to check in online, select seats, add extra baggage, or make changes to your flight via the Finnair website or mobile app. If you booked through a third-party travel agent, you might have an "agency reference" as well, but the airline-specific six-character code is what you need for the Finnair system. It is important to keep this code private, as it—along with your last name—grants access to your personal travel details and the ability to modify your flight itinerary.
