Where must the first cabin crew member (cc) be positioned for boarding?

The first cabin crew member must be positioned at the L1 door during boarding because this location serves as the primary entry point for most passengers. The L1 door, often situated at the front of the aircraft, allows for an efficient boarding process, as it typically accesses the main cabin area where a significant number of passengers enter. Positioning a crew member here ensures they can monitor and assist passengers as they board, facilitate the distribution of safety instructions, and manage the boarding flow effectively.

Additionally, the L1 door is strategically chosen to provide a clear line of sight for the crew member, enabling them to ensure that boarding procedures are followed correctly and to respond promptly to any issues that may arise. This position is critical for maintaining safety and an organized boarding experience.
