What should a flight attendant do if the lavatory trash is full?

When addressing the situation of a full lavatory trash, the appropriate course of action is to empty it. This is crucial for maintaining cleanliness and hygiene on the aircraft, as a full trash receptacle can create unpleasant odors and could also pose a safety risk should it become too full and overflow.

By taking the initiative to empty the trash, the flight attendant ensures that the lavatory remains a clean and functional space for all passengers. This action reflects the responsibilities of a flight attendant, which include upholding health and safety standards onboard.

While reporting to the captain or disposing of it at the next airport might seem like reasonable responses, those actions do not address the immediate issue at hand. Leaving the trash remains unaddressed and could lead to further complications. Thus, emptying the trash is the most effective and proactive step to take.
