Yes. You would also have up to 6 flights and 2 stopovers available in NA, so you could have a trip to ORD or NYC or where ever any time in the 12 months after the first flight (subject to the 16 segement limit on a DONE3)
3) If so, where can I plan an itinerary as I can't seem to plan RTW's on AA'a site?
Use the AA & Oneworld timetables as a starting point and put all into a spreasheet or list.
A flight LAX-LHR-EDI-LHR-LAX may be cheaper than a a DONE3 RTW.
