Hi all,
Just wondering if anyone has any suggestions on how to further optimize this DONE3, and clarification that it is in fact valid (Mileage Monkey says so, but I'd rather let the experts take a look

)
ARN-MAD-DME-ORD-SEA-JFK-DFW-ANC-DFW-JFK-SYD-NRT-SIN-NRT-SIN-LHR-ARN
Currently comes out at 54260 miles, and 2010 QF status credits.
Any suggestions?
