I will say, while this petition is abhorrent to me, I did have a related, very humanity redeeming moment recently.
Commuting home, I got what was literally the last flight i could that night, and what I thought was the last seat onboard. Sure enough, this airline’s computer system wasn't working, so capt couldn't verify my jump-seat authorization (i guess?), so just took a seat in back and crossed my fingers. When the time came, plane got full, and couldn’t sit jump-seat. As the capt came to apologize for kicking me off, a rather large gentlemen (easily 6-7, 300+) overheard him and offered to give up the extra seat, he voluntarily purchased because of his size, if i didn't mind being crowded in the middle. I was shocked he was worried about my comfort…I stood up and hid in the back as soon as sterile dinged just to give him space.
Some people are good it seems
