I have a split family booking on the same flight in different classes. I have my wife and my 11 year old daughter booked in First on one booking and me and my 2 sons aged 15 and 14 in World Traveller.

I am assuming that I can swap with my daughter and that will be fine with the crew although I did think they might have a child meal allocated in F?

I’m not looking to get into a debate about whether parents should sit separate from their children I’m just interested in whether there will be any issues with me and my daughter occupying each other’s seat. I will of course tell the crew where we are sitting but the kids are good and well behaved and usd to flying etc. FWIW I have not booked an exit row in World Traveller so no issues there.
