US: OAK/SJC - ATL ... ~580 a.i. in First.
Now granted, US domestic first is at best "Business Minus".
But at around $580 all in, not a bad run especially for BD and LH.
A little over 2300 miles each way
Bookable on usairways.com, routed thru PHX.
I haven't had a chance to play with routings, it would become a fairly spectacular fare if it allowed 4 segs thru PHL.
