1) I currently only have 30k points. I can get to the USA into Chicago or Washington on 30k points. Unfortunately the CDG>ORD>BNA is not offered as a 30k award travel ugh!

2)I can layover in Washington 1 night and get a flight early out of Washington into Nashville.

I would ideally like to get back Saturday night, but not sure if I'll be able to do that on only 30k United points alone.

I may have to pay for another flight (AA) or something. I also have plenty of Southwest points to use but I can't find anything besides that Midway flight and I don't think 3 hours is enough time but I'm not sure.
