The Korean (N) Air burger has been DNA tested and it came back as mostly pork and zero human, so United wins this by default. United is the only airline I've flown that ratchets immediate punitive behaviors if your mileage status lapses. If I lapse in status on Alaska, I lose benefits after about a year, with some certificates lasting even longer - and they simply revert me to my prior status. On United, I board last and then on the gangway, they put a sack over my head and beat me with pipes before throwing me in the bilge hold.
why is Air Koryo* on the list, korean air is great
It's the North Korean airline and it has extremely low safety and service scores. But it's way nicer than United. United Airlines once drugged me with potent hallucinogens and powerful laxatives, taped all of my orifices but one nostril shut with metal ducting tape, tattooed anti-Mongolian phrases on my forehead, burned my documents and transported me in a burlap sack to Ulan Bator because I had the temerity to ask for a whole can of soda on a 10 hour flight. United flight attendants by contract, have to eat egg kebabs and Mr. Pibb so that when crop dusting passengers, the stinging noxious bum-stingers can produce tears in passengers because they refuse to humidify the cabins.
One time I asked the United flight attendant what gate we were arriving at and she smashed me in the face with a crate of glasses from first class, breaking my nose and splinters of glass in the soft tissue under my eyes, and she said back to me in a mocking voice, "mmmwat gaaaateee are we arrrriiivvving atttt your ladyshippppp!"
One time I tried to book a vegetarian meal on the United website for our grandma's flight to a cancer institute and when I tried to pay the "convenience fee" United took control of my home title and sold it to a debt collection agency for pedophiles. When we got on the plane they served grandma a pile of raw organ meat and told her it was fine because at 10,000 feet the cabin is extremely radiated and the fauna in the organs will be sterilized.
