Which item is first checked during cabin preparation?

The first item checked during cabin preparation is typically the Rev Nap, or revenue napkin. This item is crucial as it is often part of the service provided to passengers, ensuring that flight attendants have the necessary materials ready for passenger comfort and service during the flight. It serves as an indication that the cabin is in a state of readiness for service and reflects the airline's commitment to high customer service standards.

In the context of preparing the cabin, ensuring the Rev Nap is available facilitates the smooth operation of in-flight services and has implications for overall passenger satisfaction. While other items, like crew life vests, flight deck doors, and catering supplies, are indeed vital to the safety and efficiency of the flight, checking the Rev Nap first emphasizes the immediate concerns related to passenger service and experience.
