Aerial views of Tan Son Nhat's Terminal 3 show the nearly completed structure, with the official opening set for April 30, two months ahead of schedule. Surrounding infrastructure, including roadways and overpasses, is also nearing completion.

Designed to handle 20 million passengers annually, Terminal 3 will increase Tan Son Nhat Airport's total capacity to 50 million per year.
