Do all international airports have duty-free shops ?
Duty-free shops are not present at all international airports, and their existence depends on factors like airport size, passenger traffic, regulatory requirements, economic considerations, and the availability of local goods. While larger airports with high passenger traffic are more likely to have duty-free shops, smaller airports or those in countries with strict regulations may not. Travelers should be aware that they may not find duty-free shops at every international airport they visit.
