I just booked a mixed class ticket through air canada vacations to Mexico leaving on May 11th. I was able to book business class on the way home but on the way there the system only allowed me to get premium economy as part of the package. Has anyone been successful getting a bid as part of a package? Currently it’s not even giving me the option. Would I be eligible for a last minute upgrade at check in? Or by booking a vacation package am I screwed lol
