PASSENGERTYPE

PASSENGERTYPE is a data field or classification used in transportation systems and related software to identify the category a passenger belongs to. It is used to drive pricing, eligibility for discounts, seating options, baggage allowances, and service rules in bookings, ticketing, and check-in processes.

Common categories include adult, child, infant, senior, student, and military; in many systems these are represented by an enumeration such as ADT (adult), CHD (child), INF (infant), with additional codes or labels like MIL (military) or STUD (student). The exact set of categories can vary by carrier, jurisdiction, or service type, but the concept remains consistent across travel, rail, and other passenger-facing services.

Data modeling and usage: PASSENGERTYPE is typically stored as a string or numeric enum. It may be required for purchase and is often derived from user profile data, birthdate, or accompanying documents. Validation rules check consistency with age, eligibility for discounts, and applicable fare or service rules. When a PASSENGERTYPE is specified, it informs fare calculations, seat selection, baggage allowances, and eligibility for loyalty programs or special services.

Interoperability and standards: in practice, PASSENGERTYPE participates in APIs, booking engines, and fare-rule engines. Systems map codes to business rules, and international travel contexts may align with standardized passenger type codes such as IATA's ADT, CHD, and INF to enable cross-carrier compatibility.
