Which device should be used to access flight-specific customer information before boarding?

The My Flight App is designed specifically for flight attendants to access flight-specific customer information before boarding. This application typically contains essential details regarding passengers, such as their preferences, special requests, and any pertinent notes that enhance the customer service experience. By using this app, flight attendants can prepare adequately for the specific needs of their passengers, ensuring a high level of personalized service from the moment they step on board.

While other devices and systems, such as a Cabin Management System or Onboard Computer Terminal, may have functionalities for managing onboard services or systems, they are not specifically tailored for accessing detailed flight-specific customer information before boarding. The Bluetooth Device does not serve the function of providing flight-related customer data; rather, it is a communication tool that may connect to various devices but does not hold flight-specific information necessary for ensuring a smooth boarding process. Therefore, the My Flight App is the most suitable choice for this particular task.
