Can food be taken on board?

1. According to the Catalogue of Articles Restricted to Carriage or Consignment by Civil Aviation Passengers, there are restrictions on the types of food carried: solid food can generally be carried, while liquid, gelatinous and irritating food cannot be carried. This is because when the plane flies at high altitude, the decrease of air pressure in the cabin may lead to the expansion and even explosion of liquid and colloidal food.

2. There are restrictions on the weight of food carried: different flights have different restrictions on the weight of food carried. The total amount of luggage on domestic flights cannot exceed 5kg, and each piece on international flights cannot exceed 7kg. If it is overweight, you need to check it.
