Before entering the aircraft, cabin crew must verify...

• A. That all persons present have valid ID cards and a legitimate reason to be onboard
• B. That they hold a ticket for the flight
• C. That they are wearing a crew uniform
• D. That the bag size fits in overhead bin

Answer: (A)

Before entering the aircraft, the emphasis is on security and access control. Verifying that every person has valid identification and a legitimate reason to be onboard ensures the individual is who they claim to be and that they have authorization to be in the restricted area and board the flight. This helps prevent unauthorized access, enhances safety for passengers and crew, and aligns with standard security procedures for flights. A ticket alone doesn't confirm identity or purpose, wearing a crew uniform is unreliable as proof of authorization, and bag size checks relate to luggage handling rather than entry clearance.
