Hello purplevicki5, I sorry to hear about the poor service that you received from the cabin crewmember on your LHR JFK flight. With regards to the doors to manual and cross check do you know what crewmembers are meant to do when this announcement is made? I ask, as the way you explain what she did is unclear. I am in no doubt that the crew member was doing this to standard, maybe the door selector was jammed and that’s why they called for another crew member to check. Without being there is difficult to second guess. If you know the door drills and can explain what the crewmember did wrong.
