I've got 207,000 Avios to burn and would like to use them to take my wife to Buenos Aires for a long weekend (Thurs/Friday-Monday/Tuesday) either around the MLK holiday (1/21/13) or around her birthday (3/9/13) weekend. And, btw, I want to maximize my hubby-points and take her business class as she's never flown international business.

I'm having the darndest time getting the BA site to give me anything other than mid-week flights, which won't work for us, and every time I try the route on the AA site (just to find available sAAver fares) it insists on sending me on a ridiculous route through Chicago and Miami to EZE.

I'm willing to drive to IAD or DCA to make this happen, but not having any luck there either.

Any insights from our brilliant booking gurus would be greatly appreciated!
