This happend to me multiple times when I was flying on a monthly basis with Swiss. I had the whole row for myself for about 3 hours. Its not so comfortable to lay down because of the seatbelts and the arm-holder on the window seat. I am 170cm tall and my feet were in the aisle and got sometimes hit by people. But it's truly nice to stretch my legs across three seats on the floor while leaning against the window seat. The first tray is for the notebook and the second one for drinks and food. That is truly comfortable. I increased the likelyhood of this happening to me by buying the cheapest tickets possible for a range of multiple weeks (not enough customers) and for always choosing a window seat in the last few rows. Often the seats where crowded in the beginning of the airplane but at least one middle seat was empty in the back.
