A Passenger Name Record (PNR) is a unique alphanumeric code used to identify a specific booking within an airline’s reservation system. This code, typically six characters long, serves as a digital key to access and manage all details related to a particular flight itinerary. For instance, a reservation containing information about passengers, flights, connecting transportation, and special service requests might be associated with the record locator “ABCDEF”. Displaying such a code in an educational context allows readers to understand its form and function.
These identifiers play a critical role in the smooth operation of modern air travel. They enable efficient management of passenger data by airlines and travel agents, facilitate online check-in processes, and are essential for accessing real-time flight information. Historically, these codes were primarily used internally by airlines. However, with the advent of online booking platforms, they became crucial tools for passengers to manage their travel arrangements directly. This shift empowered travelers and streamlined various aspects of the travel experience.
