Several low-cost airlines charge for carry-on luggage, hidden baggage fees in low-priced air tickets.

Recently, many civil aviation passengers have reported that they brought a 20-inch "carry-on suitcase" on board the plane, but were stopped at the boarding gate and asked by the airline to pay the corresponding luggage fee in order to bring the luggage on board. Moreover, different airlines have different standards. The situations reported by passengers are mainly concentrated in low-cost airlines such as Spring Airlines, Lucky Air, and Capital Airlines. Industry insiders explain that China's airlines are generally divided into full-service airlines and low-cost airlines. Full-service airlines include many service items in the ticket price, such as a larger free baggage allowance, free meals on the plane, and free accommodation in the event of flight delays. Low-cost airlines have lower ticket prices, but services such as baggage and meals need to be paid for separately. Differential luggage services are not unique to China, as many airlines in the European and American markets also provide lower ticket prices for passengers who do not need these services. Experts also remind that airlines have an obligation to provide relevant information, and passengers should pay attention to the airline's related instructions when purchasing tickets. In addition, the journalist also tried to search for ticket information on multiple mainstream online travel booking platforms, and the information displayed generally includes the luggage standards for the corresponding fare. Some platforms display the excess baggage fee standards and provide links for passengers to purchase additional baggage allowance.
