Simply put, it is a box lunch, which is an airplane meal delivered on the plane. Boxes of quick-frozen food prepared by the central kitchen are thawed and heated in the oven on the plane, and then delivered to passengers one by one by the stewardess.

Economy class usually provides only one set meal, but first class or business class usually provides appetizers, main courses, desserts or fruits separately. Even if Singapore Airlines can't provide chef's ordering service, there are generally two or three kinds of dishes to choose from, including Chinese food and western food, while western food is mostly beef and mutton chops, and economy class selection is generally not provided.

If passengers have food allergies (such as not eating seafood, milk, peanuts, etc. ), they also need to inform the airlines in advance to see if it is necessary to match the special meal. If you are still hungry after eating, you can ask the stewardess for another one. On most flights, airplane meals are overloaded. First, it is to prevent some meals from encountering unexpected problems (for example, the stewardess accidentally slipped when picking up the lunch box). Second, on flights that can choose meals, it can also give more passengers the possibility to choose. So many times, the side dishes will not be served too much, and the main course will be served several times.
