We're going on a 9 hour return flight with 8 hour time difference on other side, my partner flies a lot and can has free upgrades he can use to put us all in business class, the kids are aged 10 and 12. A couple of the upgrades will likely expire without being used if not used on this trip. I initially said no way to the kids flying business class. Just because of uncomfortable feelings around spoiling them, that it should be something you work for/don't get at that age etc etc. I am aware of how privileged they are in many ways in their lives and this seems like a huge extra thing in that regard.
Partner thinks that it makes sense as we"ll all be a lot more rested on other side and on return.
Wouldn't go business class and leave them in economy at this age, but have suggested one of us stay with kids one each leg and the other goes business class. What would you do?
