I know I’ll likely get vilified for saying this, but personally I don’t think there’s a place for infants in an F or J cabin. Between the possible disruption they may cause when someone has paid thousands of pounds so they can sleep on a flight and the fact that copious amounts of alcohol are being served, I personally don’t think it’s a good environment for a very small child.

I flew back from Chicago in J 2 years ago and a mother & father with 2 toddlers were also onboard. Both spent the entire overnight flight screaming with the father walking around the cabin trying to settle them as the mother ignored it. The crew were clearly exasperated but said nothing. The remainder of the business cabin were furious.

Im aware some airlines (MH?) limit children from their premium cabins, for me more airlines should be brave enough to take this step

Just my 2c
