Does the priority boarding benefit that comes with carrying an Amex Delta credit card apply when boarding other SkyTeam airlines while connecting in Europe? My connecting boarding passes never indicate SkyPriority or Zone 1 boarding.
I always explain and show the GA my Amex Delta card and never had issues getting into the SkyPriority lane while in Europe.
Not sure if the information doesn't get shared properly between partners, or maybe perhaps the benefit applies only to Delta-operated flights?
