Hi I am flyting to PVG in about a month, and I am looking to spend extra to secure a preferred seat? What is the best Y seat overall on the 400 seat configuration?
Also how about the regular seat 61B? Is it better than a regular middle aisle seat?
I have never been on a new seat configuration 777 yet.

Right now 18B is available, 51 A,B,J are available
All the middle preferred seats are wide open.


Also a side question, do they still allow us to check into those preferred seat at online check in? (You know, trying to save that $120). That being said I am 6'4 tall, so really need extra legroom.
