Howdy all, my first adventure here. My hope is that someone can direct me to a web site which can inform me the percentage full/empty any given flight. On long hauls, >12 hrs in plane, nice to lie flat without Business class ticket. Often on very early departing am flights, the wee hours, fewer travelers and more empty seats, maybe 3/4 across near the rear of the plane suitable to sleep upon. I will be traveling from USA to Hong Kong post knee surgery and I'm a tall guy. Are such records as 'number of passengers on flight' public info or kept private? thnx
