Hello everyone... recent addict to these forums posting for the first time.

I'm an American living in Australia.

I'm about to book a ONE RTW fare starting in Australia, through the US and on to Europe for conferences before ultimately returning to Australia.

My goal is to maximize accrual of AA FF miles, and do the platinum challenge during this trip.

I've been speaking to an agent here in Australia, who has informed me that I should be able to book on all AA coded flights regardless of the hardware (subject to availability of course). This is important to me of course since the trans-pacific and trans-atlantic flights are going to be my biggest segments. Since I'll definitely be flying Qantas hardware from SYD-LAX it's important to me to get the full miles for that flight. To my knowledge, ONE fares are supposed to be booked in "L" class on all carriers. An L fare on QF will get me 50% miles, but an L flight on AA codeshare will get me 100% (my interpretation).

Has anyone been in this situation before? I've read the FAQs and my interpretation of this would seem to indicate that it shouldn't be a problem, but I'd be thankful for any experiences or warnings from other flyers.
