What should the "A" FA do after confirming the door seals are flush?

The correct action for the "A" Flight Attendant after confirming the door seals are flush is to perform a visual cross-check on the opposite door and confirm this with the "C" Flight Attendant. This procedure is essential for ensuring the safety of the aircraft and its passengers. By confirming that both doors are properly sealed and operational, the crew can help prevent any potential issues during takeoff or flight.

The visual cross-check serves as an additional layer of verification that promotes safety and compliance with standard operating procedures. This teamwork and communication among crew members is crucial in aviation, as it minimizes risks associated with door failure or other complications.

While preparing emergency landing procedures, conducting a pre-departure briefing, or starting the in-flight entertainment system are important tasks, they are not the immediate priority following the confirmation of the door seals. Ensuring all exit doors are secure is fundamental before proceeding with other flight operations.
