This document provides an introduction to travel technology, discussing key concepts like passenger name records (PNR), central reservation systems, codesharing versus interlining, married versus passive segments, and stopovers. It also covers the differences between direct bookings with airlines versus bookings through global distribution systems (GDS) like Sabre, and the rise of new distribution capability (NDC) standards. The goal is to explain fundamental industry terminology and technologies to understand how flights are booked and scheduled.
