Even though Nha Trang has it’s own airport, the major airport that people use to fly to/from Hanoi and Saigon is about a 30 minute drive to Cam Ranh. The Cam Ranh International Airport is very interesting. There is just one functioning ticket counter due to the small number of flights. I love the coffee shop on the first floor. Since it is packed at the gate, I stay down here until about 30 minutes before my flight leaves. It is more comfortable.
