According to the regulations of the Civil Aviation Administration of China, the sum of the three sides of the passenger's carry-on baggage can't exceed 1 15cm, that is, the volume can't exceed 55cm×40cm×20cm, that is, 2 1 inch (including handles and rollers). Overweight baggage can't be taken on the plane, so it can only be checked as soon as possible. Generally speaking, the suitcase is less than 22 inches and can be carried with you.

Extended data

Generally speaking, luggage can be divided into soft cloth boxes and hard boxes (hard boxes can also be divided into ABS boxes and PP boxes). According to the structure, it can be divided into two types: vertical pull rod and horizontal suitcase. According to the size can be divided into (from small to large): 18 inch, 20 inch, 22 inch, 24 inch, 26 inch, 28 inch, 30 inch.

When purchasing a travel soft box, first of all, we should pay attention to whether the zipper is smooth, whether there is tooth loss or dislocation, whether the stitches are straight, whether the upper and lower lines should be consistent, and whether there are empty stitches or skipping stitches. Generally, there are jumpers at the corners of boxes. Secondly, it depends on whether the box and the surface of the box are incomplete (such as broken warp, broken weft, broken silk, etc.). ). The inspection method of tie rods, wheels, box locks and other accessories is the same as that of purchasing a suitcase.

The suitcase can be carried or dragged. The wheels of the suitcase we usually use are basically located at the bottom of the suitcase, but modern people have designed a new type of suitcase, which is designed to be cylindrical and the wheels are wrapped around the outside of the suitcase. This kind of roller design makes this suitcase better adapt to different terrain, for example, it can easily go up and down stairs by pulling the box directly.
