I'm 6' 4" and sat in the main with another 6' guy in the 2nd J/S on WN for 1.5hr. It was painful for me so I can just imagine how it was for the other guy. At TOC I volunteered to go "stretch my legs" in the galley and we all mutually agreed that I'd return for the final approach. I was and will be eternally grateful for the ride but never again if I can help it.
