I'm right on with MSPNWA's view. I really like these seats. I had been warned that one drawback was people lining up in the aisle for a lav visit, but not once did that occur during my flights. There is no way to lean against the wall/window to sleep but very comfortable in comparison to a 3 seat row. Nice and private seat area to enjoy with a traveling companion (if you have one) but my best ticket purchase ever.....2 cheap Y tickets roundtrip and I rode in those 2 seats alone. Almost as good as business class at a rock bottom price. A pillow, blanket and arm rest raised and I stretched out all the way to NRT
. Continued on to GUM on a 767 with 2 seats to myself so it was a great alternative to buying an expensive J ticket and enjoying the space and comfort of just doing "my own thing." Free beer and wine, decent food and 3 airline magazines and I was in heaven! I did not have any turbulence issues although you do feel a bump, a sway and a bit higher noise threshold but I still rank them some of the best seats on a 747 if flying Y.
Enjoy your trip and ride,
watch what you want. you may get it.
