This. With kids that age you have plenty of trips that will be just you in your near future.
Also if your concern is about them being entitled, I actually think dangling it in front of them like that will make it worse. They may resent you getting this luxury experience they aren't allowed to participate in, and start thinking of it in weirdly entitled ways like "ok fine I guess only adults get to fly in business class, well when I'm an adult I will fly business class." But that's not how it works. They aren't going to get the nuance of you having worked for decades before you could afford something like that -- kids lack perspective by definition. They are just going to see their parents having an experience and excluding them and it might make them fixate on the difference when, in the end, it's honestly not that big of a deal to fly business class. It's nice but you're still on a plane.
I'd just fly premium economy together and plan on some nice luxury travel just the two of you soon.
