The last time I flew in a plane with a door issue was in 2016. Our United Airlines 767 aircraft had a problem with one of its rear emergency exit doors which had to be repaired in the USA. The door was not operational but the plane was still considered air worthy. So before the plane was loaded with passengers at Amsterdam, the plane’s carrying capacity was cut in half by declaring a huge section of economy seats in the back nearest the problem door as no longer “usable”. The affected seats were taped off and no one was allowed to sit there during our transatlantic flight to Chicago. Yeah, a lot of passengers had to be assigned to different flights. I was one of the unaffected passengers.
