What does "no-op" signify in the context of flight operations?

In the context of flight operations, "no-op" signifies a flight that will not operate. This term is commonly used in the aviation industry to communicate that a scheduled flight will not take place as planned, which can occur for various reasons such as cancellations due to weather, mechanical issues, or scheduling conflicts. Understanding this terminology is crucial for flight attendants and airport personnel, as it impacts passenger communications and operational planning.

The other options refer to different situations: a delayed flight indicates postponed departures, overbooked refers to flights with more reservations than available seats, and an extended layover addresses longer wait times between connecting flights. Each of these scenarios has distinct implications for passengers and crew, but "no-op" specifically denotes a complete cancellation of the flight operation itself.
