CDG... the gate agents DO NOT board using your seniority. They board whomever they want, in whatever order they want, in whatever seat they want. I've seen it all there. The AF/KLM computer system doesn't talk to ours so you won't have any way to see where you are on 'the list'. They are famous for schmoozing their own colleagues or AF ticketed passengers into business or comfort plus while you get jammed into coach. I don't know what the work around for that is, but you could ask to see the departure report from the purser. Even that is produced by AF, so it's not exactly like ours... Well, bonne chance!
