My longest single flight was Malaysia KL to London England - about 13 or 14 hours nonstop. Slept for some, watched movies, read, ate. But a long time to be stuck in one small place. The plane was very big and smooth with good space and sometimes you dont know you are flying at all except for engine noise. But when you do feel some turbulence it is a bit scary to think you are still 10 hours before you can get out and you really hope the turbulence doesnt last too long. I tried to walk around every few hours to keep my blood moving in my legs
Anyone had longer single flights and how did you find them?
