Personally, I don't wipe down the seat itself, I don't really think that does anything. Once I'm seated I'll pull a Clorox wipe out of my bag and wipe down the arm rests, entertainment screen, tray table, anything else I plan to physically touch, but as far as the seat itself goes I don't bother, honestly don't really see the point of that if all it's going to touch are the backs of my clothes that I'm immediately going to change out of upon reaching my destination.

As far as the seat poaching goes, I'd downgrade the poacher back to Y-.
