What is the more common name used by TMCs for the DTS/CTO Confirmation Number?

The more common name used by Travel Management Companies (TMCs) for the DTS/CTO Confirmation Number is the Passenger Name Record (PNR). A PNR is a unique identifier that holds all details related to a traveler's itinerary, including segments of travel like flights, hotel information, and car rentals. It serves as a digital “record” used by travel agents and systems to retrieve bookings, manage changes, and ensure accurate coordination of travel plans.

While terms like Booking Reference or Trip Identifier may be used in different contexts or by various systems, the term Passenger Name Record is the widely recognized standard that encapsulates the comprehensive data associated with a travel booking. This recognition distinguishes PNR from other identifiers, emphasizing its specific role in the ticketing and reservation process.
