If you're flying to Southeast Asia, you will more than likely arrive via one of the region's three main hubs: Bangkok, Singapore, or Hong Kong, from where you can pick up flights to any other destination in Southeast Asia. Your home country's national carriers will almost certainly connect with all three of these airports. In addition, check with Southeast Asian-based airlines for fare deals: Cathay Pacific, Thai Airways, Malaysian Airlines, and Singapore Airlines. United also has direct flights between the U.S. West Coast and Vietnam.
