What is a primary characteristic of commercial airports' websites?

A primary characteristic of commercial airports' websites is the inclusion of a list of airlines that operate at that airport. This information is essential for travelers who are looking to book flights, as it helps them identify which airlines serve that specific airport, as well as the various destinations available. By clearly displaying this information, the airport website enhances the usability and functionality for customers, allowing them to make informed decisions when planning their travel.

Providing airline information is vital for fulfilling the primary role of an airport's website, which is to facilitate travel planning and provide relevant resources to the public. It enables travelers to quickly find options for their journey, check schedules, and understand the access to different destinations from that airport. Therefore, a clear listing of airlines directly aids in improving the user experience on commercial airport websites.
