I don’t disagree. Travel by air just is the worst. I did it two to four times a week for years as a business traveler. Perhaps it will add ten years to my life because I learned how to bear every delay, bother, rude event, small terror, difficulty and aspect of poor service without letting it effect me. I had to use it. My job was a good one in other regards so I learned to ignore or deal positively with a lot of it.
United was one that was so bad I found ways to avoid them as a carrier.
