On Long Haul tours which this is, then you usually have complimentary (VIP) lounge and that is where you will find the people on the tour, or if not look out for the luggage labels on bags when your checking in. There is normally a rep to see you through check in, then if the rep is travelling with you they will find you in the lounge. Unless things have changed that's how it works.
