This past September I took my mother to her homeland which she is always homesick for. My mother is 83 and I am 53. My mother was a stewardess on Swissair from the mid 1950s until mid 1960s. We booked our flight on Swiss, the spiritual successor of Swissair, as we always do. I paid $29 per seat extra so that we could sit together with a window. When the plane took off my seat went into full recline position. By itself. The 20- something Italian or Ticinese man behind started pounding on my seat. I informed him that seat was broken, not my fault. I spend next half hour holding seat back up so as to not inconvenience people behind. By fiddling with button I got seat back to finally stay in position. Too late- the youngsters behind felt that I had been messing with them on purpose and proceeded to kick and punch hard my 83 yr old mother's chair for 2 hours. I finally stood up and called cabin crew, explained situation. The Italian woman behind told crew that she would "kill me." Honestly, I did nothing to provoke this. Crew offered to move my mother and me to mid fuselage seats. I said no thanks as I paid for seats. Trouble makers should have been warned or moved. We spent next 5 hours with our seats upright. Flight ruined. I called Swiss customer service and after a month, "Ajai" offered me $100 off next flight due to malfunctioning infotainment system. Did anyone read complaint? Passenger threatened to kill me. Crew was totally ineffective at remedying situation. I wrote back to Ajain and reiterated my experience. He responded, 1 month later, that Swiss would do nothing for us at all. Bye bye Swiss after we were loyal customers for 6 decades. Swissair is gone. Lufthansa's Swiss Airlines is shabby.
