Club World overnight flights - how soon after takeoff can you convert to bed?
On a recent CW overnight flight from the US, I got up as soon as the seatbelt sign went off, and was surprised to see that a couple of the aisle passengers already had their seats made up as beds. How soon after takeoff is it acceptable to do this? I'm always trying to sleep every minute that I can on these flights, so if it's OK to do as soon as the plane leaves the ground then I'll start doing that.
