Hi, I feel like this must be a common question, but I couldn’t find much through searching.

I am booking a trip for my family of 6. I don’t have enough points to book all as award travel, so it will be 3 award tix and 3 cash tix, all on same itinerary. I am Platinum but no others have status. I would like to merge the reservations so we can all benefit from MCE seat selection and free baggage. Is there a way to do this?
