Last week I did a 13.5 hr flight to Frankfurt and then a quick 1.5 hr hop to manchester. The guy behind me on the manchester flight,kept snorting so loud to clear his nose its was gross and making me feel sick. Well I had one brwewing and decided to let it go as all the seats around me were empty and when it slipped out I used the saftey instructions to direct it in his space and yes it worked. He got up and moved t the back of the plane.
