How can I check the things I bought at the duty-free shop in Bangkok with my luggage?

The duty-free shop in Bangkok shopping mall bought something and checked it in this way, together with the luggage:

1. When you check out at the mall, tell the clerk what procedures you need to go through and provide your flight information.

The clerk will provide you with the duty-free shopping receipt and the delivery list.

Please keep the shopping receipt and delivery list so that you can show them when you arrive at the airport.

At the check-in counter at the airport, give your luggage and check-in list to the staff and tell them that you have duty-free items to check in.

The staff will check your luggage and duty-free articles and check in for you.

6. You need to pay the consignment fee, which depends on the airline and the weight of the luggage.

7. The staff will mark your luggage and duty-free items and send them to your flight. Consignment refers to the service of delivering goods to a transportation company or postal company, which is responsible for transportation and delivery to the destination.
