Question about star alliance upgrade...
So I booked a flight through Eva Air on a Y/B fare ticket.
I was upgrading the flight and it only costs 15-20K per segment (NA-SEA vice versa) in Aeroplan. Is the upgrade from economy to business class or economy to premium economy? The upgrade says Economy to business but I'm afraid it will only upgrade me to premium economy since there is a PE cabin on the flight.
Sorry for dumb question
