What key factor should be ensured before pushing back from the gate?

Before pushing back from the gate, it is essential to conduct a cabin secure check. This process involves ensuring that the cabin is in a safe and secure condition for the flight. Flight attendants check that passengers are seated with seatbelts fastened, all carry-on luggage is properly stowed, and that there are no objects obstructing aisles or emergency exits. Conducting this check helps to promote passenger safety and ensures compliance with regulatory and airline safety protocols.

While the final headcount of passengers is important for accounting, and confirming all luggage is loaded is necessary for flight operations, the immediate priority is ensuring the cabin is secure for a safe departure. Similarly, while the flight plan approval is crucial for overall flight operations, it is not a factor that directly impacts the security and safety of the cabin environment at that moment.
