Also going to say if anyone asks me to change seats for this (and wouldn’t involve me separating too much from my own co-travellers, and even then, we’re adults that can deal with a few hours apart on a trip together), I’ll 100% do it.

Absolutely nothing wrong with asking. Worst that should ever happen to anyone making a reasonable ask is a “no”. I’ll enjoy being a part of the snub against the airlines and their junk fees.

I fly often enough that I don’t really care for my aisle/window/whatever seat if I have one. They’re all pretty much the same.
