This specific designation refers to a scheduled passenger flight operated by Southwest Airlines, identifiable by the numeric code 461. Such codes are essential for air traffic control, scheduling, and passenger information systems, allowing for precise identification and tracking of individual flights within a vast and complex global network. This numerical identifier distinguishes it from other flights operated by the airline or other carriers.
The use of a standardized flight numbering system provides crucial organizational structure to the aviation industry. It facilitates clear communication between airlines, airports, and regulatory bodies, contributing to efficient operations and passenger safety. Historical flight data associated with a specific number, such as route information, departure and arrival times, and aircraft type, can be valuable for operational analysis, performance tracking, and incident investigation.
