Booked this for my mom a few weeks ago and got pretty much what I want; just need to book a revenue ticket to match now (mix of J/Y hoping to upgrade on AC).

This is for late April early May
EWR-ZRH (UA F) (stop)
ZRH-FRA-ICN (OZ F) (stop)
ICN-NRT (UA F)
NRT-YYZ (AC J)
All-in: <$400
Is this a good deal?
Not a lot of stops but managed to get F for her. I think UA F is a good product so willing to go for it and LX wasn't yet available and I wasn't willing to sacrifice losing F or availability on certain segments, plus considering I'm buying a revenue matching ticket need to consider which airlines give the best deal for J and chance to upgrade to J on AC as E. In my limited experience I feel OZ gives the best J fares from Europe and to NA for the service.
Heard OZ has a great soft/hard product and I hope OZ F would be amazing. AC2 on J is a good product and you get good sleep so I think that's a good choice. Don't want to go through the US and NH J/F wasn't available so no point to do that routing.
