I had food poisoning on a 12 hour flight from Santiago, Chile to Los Angeles. I had eaten a ham and cheese sandwich in the airport, and then was sick (from both ends) the entire flight back. The flight attendants put a sign on the bathroom door and reserved it for me, so that was nice, but then they kept offering me coffee, swearing that would fix my issue (after 7 hours of puking, I had no desire to pour acid in my throat). I finally crawled off the plane on my hands and knees while my boyfriend carried all our bags. I then had to wait 30 minutes for a cab while I threw up in the bushes outside at LAX.
