Which of the following does YVR NOT use to communicate with passengers?

Vancouver International Airport (YVR) utilizes various modern communication methods to keep passengers informed about flight status, airport services, and other important information. While the airport does engage with passengers through email notifications, social media updates, and digital displays throughout the terminal, it does not typically rely on direct telephone calls as a primary means of communication. Instead, YVR focuses on digital and online platforms to ensure swift and efficient information dissemination. This approach allows for the instantaneous sharing of updates and alerts, catering to the needs of a diverse and tech-savvy passenger demographic.
