Twenty years or so ago, I flew on an American flight from Dallas to Dayton on a RJ seated next to a guy who was at least 400 lbs. I had the window seat, he had the aisle. He was so big neither of us could lower our tray tables. Think "Fat Albert" big. I kept trying to get the stew's attention, but she ignored me, then finally shook her head "no" when we made eye contact. And yes, he ordered a diet Coke.
I exchanged correspondence with American over the incident. I was told they do not want to embarrass their "plus size" (also used the term "robust") customers as they had passengers right just like everyone else. Long story short, I got no apology but did get a $300 travel voucher that expired before I could use it.
Airlines solution to everything is to just send a travel voucher.
I had a flight canceled. The airlines policy was to give $400 to each person. My wife and I rebooked on a different airline. I never received a check, so I kept callling and sending emails. They seemed to not even bother to read or listen to what I had to say. I kept getting $100 vouchers. To the point We were able to book airline tickets to Vegas for nothing. Eventuallly they finally sent us a check, with yet another $100 voucher for being late.
I hate flying. Delays, cancellations, crying kids, parents who let their kids kick seats and run. People who want to take their shoes off, people that need to get up 4 times every hours to piss, stinky food eaters, etc etc.
