Hi flyertalk,

I've booked tickets for my family on Emirates this summer. My wife and I will be in F, my sister will be watching our older daughter sitting separately, I booked them in Y and am trying to upgrade to J with miles. We have a baby also who I need to ticket as a lap infant. My question is, can I add the baby to my sister's reservation to pay a lower ticket cost (10% of the cash fare, much less Y than F of course), so baby would be ticketed in Y or J depending on upgrade availability, and then bring the baby into the first class cabin with me and my wife? Anyone have insight into how accommodating Emirates might be with this?
