1. Check the airline regulations: When buying a ticket, the airline will tell you which sizes of luggage can be checked and which hand luggage can be carried free of charge during the ticket purchase process. You can check your ticket information, or consult airline customer service to understand the relevant regulations on luggage.
2. Check airport regulations: At airports, there are generally relevant regulations and standards. You can check the announcement of the airport or consult the airport staff to understand the baggage consignment regulations.
3. Pack your luggage reasonably: If your luggage exceeds the regulations of airlines or airports, you can consider putting some items separately to reduce the size and weight of your luggage. In addition, avoid carrying prohibited items, such as flammable, explosive and sharp items.
4. Arrive at the airport in advance: If you are not sure whether your luggage meets the consignment standard, it is recommended to arrive at the airport in advance so as to have enough time to pack your checked baggage.
5. Understand the baggage service: At the airport, there is usually a baggage service desk, which can help you deal with baggage problems, such as lost, damaged and overweight luggage. You can learn about these services in advance so that you can ask for help in time when you need it.
In short, if you are not sure whether your luggage can be checked, I suggest you consult the airline or airport staff in advance so as to check your luggage smoothly.
