I finally called to reserve my DONE4.
To my surprise I had a problem with the very first segment SFO-ORD D class for March of next year.
Since I am connecting this with my SFO-AKL-SFO pricing error

the dates and times mattered to me.
I have looked at expertflyer and as of now AA has not sold even one first class seat.
I know there are 'special rules' for the first flight on a RTW itn [I am confused some with the rules actually].
What would you do...wait list or just forget about this segment [and buy it as part of a separate ticket]. [I need 5 A seats]
What happens if the inventory never becomes available?
