Old LH 747-400 had the 8 first class seats in the upper deck, each having both a seat and a dedicated bed next to it on the window side IIRC. Laying right next to the window which has a slight angle also had amazing night sky views. Someone who experienced it said it was as close to flying private as it would get, as this was before the suites & walled off seats became more common. Reply reply …
