I have a question regarding boarding positions when the CP holder is not A-list but the companion (me) is A-List.  From what I have previously searched (if I read correctly), I would get a decent A position due to A-List status, and the CP holder would receive a position behind mine (eg. me A18 and CP A19).  Assuming the CP holder did not purchase Business Select and the CP adds me to the trip well before 36 hrs prior to departure, is my understanding correct (we both would receive priority boarding positions)?   Reason I ask is that I have been seeing examples (more than just a few) of passengers where the boarding was NOT sequential.  Some have chalked it up to a system fluke, but when I see more than a few I don't know if I would call that a fluke.   The flights we plan to travel on are long so I just want to make sure I'm clear on whether we should consider EB or some other alternative to ensure that we board relatively early in the process.   Thanks! ...
