What does a 'spinner' refer to during boarding?

A 'spinner' refers to a passenger in the aisle without a seat assignment. This term is used in the context of boarding to describe a situation where a passenger is unable to find a designated seat, often leading to congestion and delays during the boarding process. It highlights the importance of efficient boarding procedures to ensure that all passengers are seated promptly, allowing for a smoother departure.

In this context, the other options do not accurately capture the meaning of a 'spinner.' A flight attendant requesting a seat assignment does not fit the definition since it pertains to staff activity rather than passenger status. Luggage handling equipment is unrelated to passenger boarding and requires different terminology, while a delayed flight operation is focused on timing rather than specific passenger behavior in the aisle. Understanding this terminology helps flight attendants manage the boarding process more effectively.
