Seeking kind advice if this is a legal DONE4:
OSL-DOH-DFW-GRU
GRU-DFW-ANC-LAX
LAX-JFK-HND-SIN
SIN-NRT
NRT-BLR
BLR-NRT-DOH-CMN
CMN-DOH-OSL

Also wanted to ask, about half of the segments I intend to fly only more than a year out from now i.e. if I booked now I would need them to be open dated first and then booked later, do the members here who help book DONEx help with booking the open dated segments later, or would I need to go to Propellor Travel or some high service TA?

Thanks in advance!
