AITA?

Small region flight -last one of the night- this past Saturday. Each row is two seats **aisle** two seats. 20 rows.

I’m in my preselected paid in advance aisle seat. At least one full empty row that I can see. Last dude gets on plane. He’s assigned the seat next to me. I get up, he sits down, I try to sit down. He takes up his seat and more than half of my seat. I’m pushed into the arm rest and leaning halfway into the aisle. He is sweating profusely and it is soaking into my clothes. My pants are drenched instantly. He’s uncomfortable, I’m uncomfortable. Plane door is not closed. He asks FA if he can move to empty row. She says he has to wait until everyone has boarded. (I think he was the last one?). So he waits. Then he asks another FA if he can move to an empty row. She glances to the front says oh it’s way too late for that and keeps walking. We’re stuck.

For the hour flight I’m frozen into 1/4 of my seat and forced to lean into the aisle. He falls asleep and proceeds to spread out even more and sweating non stop. I say nothing but die inside while my clothes continue soaking up this person stinky sweat. I say nothing. People in row behind me spray peppermint aromatherapy over our heads. So grateful, I could’ve cried. Flight lands. I go home and immediately file an official complaint to delta for having to pay for a full seat while only able to sit in less than half of it.

Their response was to offer 5000 sky miles (worth $45?) or 1 year subscription to paramount +. ($138). And they state they are being generous because they really don’t have to offer anything. I refuse both offers. Not flying delta again if I can help it so don’t want the miles. Paramount is owned by CBS or vice versa, whatever, but not interested on principle.

AITA for being ticked off at their response? If I had stood up and refused to sit in my seat I would’ve been kicked off the plane for sure. Doesn’t the responsibility reside with Delta for assigning him that seat and then not letting him move? Is there any other recourse I can take at this point other than just not flying with them again?
