Any guess whether this is a valid award booking route ?

YYZ-EWR/BOS-LIS-CMN (stop)
CMN-IST-KTM (stop/destination)
KTM-BKK (stop)
BKK-NRT-ORD-YYZ (end)

Does the destination stop have to be the farthest point from my origin (YYZ) ? In which case, I should swap the order of the KTM and BKK stops because BKK is farther from YYZ than KTM ?


Thanks
