Onboard catering refers to the provision of food and beverages served to passengers during a flight. Airlines often offer a variety of meal options, which can include snacks, full meals, and special dietary choices. The quality and selection of onboard catering can vary significantly between different airlines and flight classes, such as economy class and first class. To ensure a pleasant dining experience, airlines typically collaborate with catering companies that specialize in preparing meals suitable for air travel. These meals are designed to withstand the unique conditions of flying, including changes in temperature and pressure. Additionally, many airlines allow passengers to pre-order meals, enhancing customer satisfaction.
