United or AA is the way to go. You'll have to check both and the costs of their Biz or F class tickets and if they are discounted for your specific dates.

I haven't used any of my USairways miles yet but from quickly reading it doesn't seem like you get much value for international flights in which you rely on their alliance award charts.

So yes, xfer those UR points to United.

If you are lucky a 1way F on united would be 67,500 miles That is if you can find one. (I found 1 available during may 2014)
econ 30k
biz 50k more available vs F and cost a little less miles.


I did a quick search and 62.5k AA miles = F and seems to be a LOT more available vs. United F during may 2014 so you may want to go with AA.
