I’m sitting in 12F. Crappy seat in a 320. I was able to SDC so I’m not complaining. I’m in group 2 so I get on early and put my backpack (my only bag) in the bin. Woman in last boarding group comes on with a big roller headed further back. Stops at 12 and asks “who’s backpack is this? Do you mind putting this on the floor in from if you?”

I politely said “sorry, but no”.

What would you have done? I’m 6’1” and need every inch of this coach seat.
