Be careful of your terminology when you speak with air carriers about this.
Your "allowance" is the allowance for the marketing carrier of the first segment of the ticket. Under US law, that carries over to all segments of this ticket. But, because you have a "waiver" of certain requirements, that waiver is not mandated by US law, although it is typically honored across alliances.
If you ask about "allowance," a precise agent will tell you that it is the same. That is not the complete answer.
