Then I guess you've been lucky. "personal experience" refers to my own trips where if there are no unresolved maintenance issues and we have the Gendec from the chief purser the door is closed....also deadheading trips where we are always allocated seats on the upper deck. There is both policy and personal choice...there are a number of reasons (some valid) why policy might not be followed....I prefer to not have to answer those questions.
