What seat should I sit in on an airplane to get the best view?

Well check in super early and get an "A" boarding group. Then sit behind the wings in a window seat. If you sit in the front rows, that's where all the pre-boards sit and you'll have a screaming kid at some point in your journey. If you sit in the back, you can see all the surfaces of the wing moving in flight and it's a bit quieter as far as screaming kids. It is a bit louder since you're behind the engine, but hey, everything has its price.
