1, quality
The quality of the trolley case is not only the durability of the material of the luggage, but also the durability of the components including the handle, the tie rod and the pulley. Because most of the travellers use luggage in the way of pulling, if there is a quality problem with the pulley, the lever or the handle, it will inevitably cast an unpleasant shadow on the journey.
2, the choice of wheels
Many brand bags are equipped with universal wheels, which can be pushed flat. Compared with two-wheel bags, they can only be pulled on one side. The universal wheel is relatively more convenient to use. When you try it out, you can understand whether the bag wheel is flexible or not, and you should try to buy a pulley with a bearing.
3, the inner part
Whether there is clear stratification inside the bag, such as wet and dry tiering, folding clothes bag, hanging zipper bag, file storage, laptop bag and other areas, users choose an obvious product according to individual needs.
4, size
Mainstream bags are mainly 18, 20, 22, 24, 26, 28 and 30 inches. The Civil Aviation Administration of China stipulates that the weight of the individual checked baggage cannot exceed 50 kg per piece and the volume cannot exceed 40 × 60 × 100 cm. Baggage exceeding the above requirements must be obtained with the prior consent of the airline. The weight of self-care luggage should not exceed 10 kg, and the volume should not exceed 20 × 40 × 55 cm.
