The city or airport where a passenger begins an air journey is the starting point for their flight. For instance, if a traveler flies from New York to London, New York is their point of origin. This information is crucial for airlines, airports, and passengers alike, primarily for logistical and planning purposes.
Knowing the origin city allows for efficient resource allocation at airports, accurate flight scheduling, and proper baggage handling. It is essential for security screenings and customs procedures, contributing to a smoother travel experience. Historically, this information was even more critical before widespread digital record-keeping, often relying on physical manifests and meticulous tracking at each departure location.
