I said charter or own. Wealthy people often charter. Who said anything about interacting with plebs? This thread is about mother freaking babies on this mother freaking plane! :) Now, if you think the definition of plebeian is just someone who has a crotch goblin traveling with them, that's a totally different problem for another post. Your assumption first class is only for the rich is in error. It might be someone with some savings, but very likely not rich. What is your definition of rich?

Now, as to you being angry and just wanting to use your child to piss off other people, keep that doing that. See how that goes for ya. While rare, parents have gotten themselves banned from airlines for being terrible people. Let's see if you fit that bill.

No. Just don't go. You chose to raise a child, part of that includes not dragging them where they don't belong until they are old grown enough to behave. If you have to go, arrange care for the child while you are gone if they aren't mature enough yet. Bringing a baby on a plane says, "I refuse to pay money to take responsibility for my choosing to have a child, so I'll bring it with me and put that burden on everyone trapped with me on a plane." Gee thanks.
