I am looking for a trip to Europe from YQR to ZRH and/or FRA in May, ideally in Premium Economy. I am getting some favourable fares in J to get there but then the return trips show very high fares, whereas if I select PE then the return fare are more balanced. I have not seen this before, and if course now I am wondering if there is a way to select the J fares but also get more reasonable (PE) fares for the return?
