I'm Looking for ways to use SWU and an $800. voucher on AA.

One option would be coach to business UG on AA154 ORD/NRT, out April 1, 2012 back April 8 - 5 full days.

What do you think?

The ticket is pricing out at $1,267. After the voucher we'd pay $934. out of pocket for two people ($467. each)

What can I expect in business class 777 ORD/NRT?

We've lived in Japan before, so this is mostly about SWU use, J class on AA 777 ORD/NRT and overall value.

I mean, ORD to Europe is pricing out the same over spring break as NRT and both exchanges rates are miserable. So, I'm thinking if you're going to use a SWU, use it on the longest flight possible.

EXCEPT: I'm thinking it's a better "bump" to F Europe for 8 hours than J NRT 13 hours.
What do you think?

Thanks for any comments or suggestions.
