Thanks Chris for the links. And thanks Al for the suggestions. I am with Southwest. I have lots of experience traveling within the USA. I did learn this summer how to get back-up tickets on other airlines to assure my arrival back home from our trips. I have no experience traveling outside of the USA. So all your suggestions are a great help to me. Also,if you could please move Australia alittle closer to the USA it might make it easier for me and my son to get there :-)
