Generally, meals are provided for flights based on departure time and flight time. For example, flights taking off before 8:00 in the morning will be provided with breakfast, flights taking off or landing before 11:30-13:00 will basically be provided with lunch, and flights taking off or landing before 11:30-13:00 will be provided with lunch. In the evening, 17:30-19:

Dinner is included on flights departing or landing between 00:00 and 00:00.

However, airlines will also provide meals based on the catering companies' capabilities. For short-haul routes with a flight time of about one hour, they will only provide snacks or biscuits.

For international routes, one meal and two meals will be provided based on the length of time.

So you can’t tell whether meals are included or not by just looking at the flight number.

Extended information: Airline meals are meals provided to passengers by civil aviation aircraft during the flight.

In-flight meals are set by the airlines and are generally provided by agencies designated to provide in-flight catering. They are prepared near the airport and delivered directly to the aircraft. When the aircraft is stable during the flight, the flight attendants place them on trolleys and distribute them to passengers.

?Flight meals in different classes of passengers are different in terms of dishes, portions and costs.

First-class and business-class airplane meals try their best to imitate high-end restaurants in terms of food and dining procedures. Even so, they are always different from real restaurants.

Economy-class airplane meals are similar to fast food. Distribution efficiency, storage volume, and cost are the main considerations. Of course, the taste of the food cannot satisfy passengers' high expectations.

There will be national standards for airplane meals in 2014, and the shelf life cannot exceed 36 hours.
