sorta similar question
My wife (MVP) and kid are going to be traveling on an award ticket and we need the baggage benefit for the kid as well, but on alaskaair.com it says that all passengers have to be on the same PNR to get the waived baggage benefit...if I book 25K awards from my account (for the kid) and my wife's account (for her), is there any way to combine them into one PNR or combine the miles at booking in the first place?
