Here's a great tip that can save some people hundred of dollars.All international flights have entry points. From these entrypoints if you need to catch a flight to your final destination, have your foreign spouse or fiancée check with a travel agent on the cost of the domestic flight. Purchasing this ticket through a local travel agent instead of including it with your international ticket could save you some money.

Before my spouse received a Visa to come to the U.S., I made two trips to China. On the return flights I needed to leave once from Beijing and the second time from Shanghai. My wife and I took domestic flights from her home to these great Cities where we spent a couple of days taking in the sights and great food. This is
something you can possibly plan into your trip.
