There are 4 of us on a 4 leg trip. Two are gold and the two kids are GM. Our flight on Easter (leg #2 ) is empty. It shows R8 and the map has 10 F seats available. Right now there are only 6 people in E+ (and we are 4 of them). Do I need to split the PNR into 2 PNR's, one gold and one GM each? If I dont clear at 48hr's and ask to be split, do the 2 children get prioritized as Gold, or as a GM? Does this have any downside to the return legs?

Thanks
Ploo
