Before arriving at international locations, which items must be sealed in service carts or atlas containers?

Liquor must be sealed in service carts or atlas containers before arriving at international locations due to strict regulations governing the transportation of alcohol across borders. These regulations help ensure compliance with various legal restrictions related to the import and export of alcohol in different countries. Sealing liquor also prevents tampering and helps maintain safety and security during the flight. As a result, it is important for cabin crew and airline personnel to adhere to these protocols when handling liquor on international flights.

In contrast, food items, inflight magazines, and electronic equipment do not have the same stringent requirements. While food items may need to be stored securely to prevent spoilage or contamination, they do not typically require sealing in the same manner as liquor. Similarly, inflight magazines and electronic equipment are generally not subject to international customs restrictions that necessitate sealing.
