First Vacation in Years
I have 4 unrestricted SWUs that will expire at the end of February 2012. I want to take my girlfriend and 17 year old son on a one week trip in the beginning of February. I'll have about 120k miles in my one pass account, and my status is 1K/Plat. I've never traveled outside the continental US. I'm thinking I'll pay for two economy tickets, and then try to get a reward ticket, or at least use some miles/$$ to upgrade my son's ticket. One thought was to go to Japan, since we are all interested in their culture. Another was to go to South Africa, where the weather will be nicer (but can I use my SWUs to get there?) Any other destination advice is appreciated. A final factor figuring into my plan is the likelihood I'll pick a route where I'm actually upgraded.
Any veteran flyers with advice?
