According to the indicator for domestic airports, King Saud Airport had the least number of complaints filed with GACA, with a rate of 4 per 100,000 passengers. There was only one complaint received against the airport and it was addressed on time. GACA explained that the issuance of the monthly report for the classification of air carriers and airports, in terms of complaints submitted to the authority, aims to provide information to travelers about the performance of air carriers and airports in resolving their complaints. It will enable travelers to choose the appropriate service provider, in addition to enhancing transparency and demonstrating GACA's credibility. It will also stimulate fair competition between air carriers and airports to develop and improve services. GACA has provided multiple communication channels around the clock to ensure interaction with travelers and airport goers through the unified call center (8001168888), WhatsApp service via the number 0115253333, social media accounts, e-mail, and the official website. GACA receives complaints through these channels about issuing boarding passes, dealing with employees, serving people with disabilities and limited movement, and others. In an effort to support its partners at the airports, the authority has prepared a booklet that includes instructions on how to deal with passenger complaints at airports. Circulated to airport operators, the booklet specifies controls and service level agreements that must be adhered to for all types of complaints and inquiries. This in addition to training employees of national airlines and ground service companies that have direct contact with travelers in executive regulations to protect the rights of customers by holding workshops from time to time. — SPA
