I think Britain is the worst when it comes to safety. Health & Safety... you can't change a lightbulb at work without filling out a risk assessment and having someone hold the ladder now... Road safety moreso (the mobile phone law - can't use mobiles while driving, a lot of speed cameras and the booster seat law which I think is ignored anyway).
in my experience, they turn the seatbelt sign off at 10,000ft and back on again when the crew announce "10 minutes to landing" on European flights or "20 minutes to landing" on the long haul ones. I've been in a hold for landing at LHR
before now and we were at about 8000-9000ft according to Airshow and they only put the seatbelt sign on when we were cleared to continue. On FI
recently, the seatbelt sign went off about a minute after take-off from KEF
but from MAN
, it was at 10,000ft. It came back on again 30 minutes before landing though.
