It appears the United ORD-PVG and Northwest's DET-NRT-CAN (Guangzhou) flights have been approved. ^

Northwest got into Guangzhou ahead of UA.
NW is planning to use 757 for the NRT-CAN route... I guess the demand may not be there initially.
It is interesting to read about AA's objection of granting the routes to UA and NW in the report.
