What does the airline code DL represent?

The airline code DL is the designated IATA (International Air Transport Association) code for Delta Airlines. Each airline is assigned a unique two-letter code which is used by travel agents, flight booking systems, and passengers to identify the airline easily. Delta Airlines, known for its extensive domestic and international routes, uses the DL code on tickets, schedules, and boarding passes to distinguish itself from other carriers. Understanding these codes is crucial for flight attendants and other airline personnel, as they facilitate smooth communication and operations within the aviation industry. Other airline codes, such as those for Air Canada, JetBlue, and United Airlines, each have their specific identifiers, which are different from DL.
