Airline brokers are professionals or companies that help travelers find and book flights at competitive prices. They work by comparing various airlines and their offerings, allowing customers to choose the best options based on their needs, such as price, schedule, and amenities. These brokers often have access to special deals and discounts that may not be available to the general public. By leveraging their industry connections and expertise, airline brokers can save travelers time and money, making the flight booking process more efficient and user-friendly.
