Airport kiosks are self-service machines located in terminals that allow travelers to check in for their flights. These kiosks typically enable passengers to print boarding passes, select seats, and check luggage without needing to wait in line at a traditional check-in counter. Most airlines provide these kiosks, making the check-in process faster and more convenient. Users simply follow on-screen instructions, which often include scanning their identification or entering a confirmation number. This technology helps streamline airport operations and enhances the overall travel experience.
