Airline codes

Airline codes are like secret names that help people identify different airlines.

Each airline has their own unique code that consists of two or three letters, and sometimes numbers. For example, Delta Airlines' code is "DL" and Southwest Airlines' code is "WN".

These codes are used throughout the travel industry to make things easier for people. When you book a flight, you will see the airline code next to the airline's name. This helps you quickly and easily understand which airline you will be flying on.

Airline codes are also used by airports, travel agencies, and booking websites to sort and display flights by airline. This can help you find the right flights more easily when you are searching for travel options.

Overall, airline codes are just a simple way to identify different airlines and make travel more organized and efficient.
