5Tan Son Nhat International Airport (Ho Chi Minh City, Vietnam)

Tan Son Nhat International Airport in Ho Chi Minh City struggles with overcrowding and outdated infrastructure, especially as it serves one of Southeast Asia’s busiest cities.  

The airport’s terminals are often packed, with long lines at immigration, security, and check-in counters.

The food and shopping options are also limited, and the general atmosphere of the airport can feel chaotic and stressful, especially during peak travel periods.
