Self-loading cargo: "Hello, Birdseed Executive Club? I've broken my leg skiing and I'm on your insurance scheme and I flew out here on your airline. Can you repatriate me and my family, please?" Birdseed: "Can you walk?" Cargo: "'fraid not - I'll need a row of three seats for me." Birdseed: "Oh dear. We don't consider it safe to carry anybody who is unable to walk on to the aircraft, so we'll have to book you and your family on Squeezy Jet."
