During the May Day holiday, duty-free shops at Xiamen Airport recorded sales of over 2.3 million yuan ($338,171), with more than 3,600 duty-free purchases. These represent year-on-year increases of 14 percent and 16 percent, respectively, as well as five-year highs for the holiday period. 

Port duty-free shops are tax-free retail outlets located in designated areas of airports, seaports, railway stations, and land border crossings, catering to inbound and outbound travelers. 

The duty-free stores at Xiamen Airport currently offer nearly 2,600 types of products from over 230 brands, including beauty and skincare products, premium tobacco and alcohol, and imported foods.

"During the May Day holiday, we launched promotions such as flash sales, customized gift boxes, and volume discounts in an effort to tap the potential of high-spending tourists, which helped keep our stores busy," said Chen Xiaodong, manager of the airport duty-free shop.

In-flight duty-free sales on international flights have also been significant. In-flight duty-free sales refer to the retail service provided by onboard duty-free shops on international and regional routes operated by airlines. These services offer inbound and outbound passengers a range of tax-free products.
