Which aircraft type must flight attendants restock the service cart after service regardless of arriving into a catering station?

The CRJ 200 is a regional jet that has unique service requirements due to its smaller size and limited onboard storage. Flight attendants on this aircraft are required to restock the service cart after each service regardless of whether the aircraft is arriving at a catering station. This is primarily because the CRJ 200 is often used for shorter flights with varying passenger loads, which may lead to a higher demand for service items.

The other aircraft mentioned, such as the Boeing 737, Airbus A320, and Embraer E175, typically have larger onboard storage capabilities and may operate on longer routes that allow for a more substantial initial stock of service items. Consequently, these aircraft may not necessarily require flight attendants to restock the cart after each service, especially if they can manage their supplies effectively for anticipated operations and route lengths. This distinction in service and stocking needs highlights the operational differences between regional jets like the CRJ 200 and larger commercial aircraft.
