I have a similar itinerary with a flying Business class to AMS with the YYC-YYZ segment in W. When I bought the tickets, it showed as Business class but after I paid, it was showing Premium Economy 😞 I think it’s because there is no Business class on some WestJet flights. (Premium Economy is the highest class). It’s misleading either way & I’m wondering about lounge access at YYC &YYZ.
