I received a notification that my seat has changed on my flight to BOS next June (my £800 flash sale bargain). It appears that the flight is now being operated by an A380 with old CW, so I've gone for 53K on the upper deck - the side facing away from the sun, direct aisle access, no-one climbing over me, several windows. The wiki says that this seat might be noisy, but it's a daytime flight so that won't bother me. This looks to me like potentially the best CW seat on the plane - anyone know better?

Aerolopa is a great resource, by the way. Thanks to everyone who created it.
