What is meant by 'RON' in the airline industry?

In the airline industry, 'RON' stands for 'Remain Overnight' and typically refers to aircraft that are scheduled to stay overnight at an airport rather than returning to their originating airport after a day's flights. This concept is important in scheduling and operational management, as it affects the planning of both crew shifts and maintenance operations.

By utilizing RON, airlines can optimize their schedules by ensuring that aircraft are available at strategic locations for morning departures without needing to reposition them the night before. It allows for better resource allocation and operational efficiency. This practice is especially beneficial for airlines that operate regional routes or have aircraft that require longer turnaround times.

Other options do not reference industry-standard terminology or practices associated with aircraft operations, which underscores why they do not apply in this context.
