I am in NYC and this is my DONE3 which I start
in NRT so I could throw in 3 round trips out of NYC
at the end of the RTW. All trips are for business.

JFK-NRT (Seperately purchased)

NRT-HKG
HKG-FCO
FCO-(LHR)-BRU
BRU-JFK This finishes the real RTW

JFK-YVR-(DFW)-JFK To YVR on CX, must connect on return
because of 1 transcon limit
JFK-BGI-JFK (BGI = Barbados)
JFK-BOS-JFK ($100 for the 7th segment, worth it becuase
same day returns to BOS can cost $450.)

JFK-HKG-NRT Not sure if I will use them, but that way I'll
have tickets to either HKG or NRT, the most likely
places I'd have to end up in Asia in the next year.
