I am not sure what to say about this really. It is something airlines, especially those offering inter-continental or long-haul flights, have to think about. They keep improving their business/first classes making it bigger, wider, offering flat beds, etc. I don't see anything wrong with it and am happy for those who can afford a business seat but at some point they should consider doing something to improve their economy or coach class. I am used to long-haul flights especially when I fly to and from home, 15+ hours approx, and economy seats are not comfortable in many airlines. I suffer for those who are quite big and can't fit in the seat. I now tend to ask for the emergency seats (when they are available) where you have a bit more room. I think British Airways is the only airline which now has another cabin: Premiun economy, with wider and more comfortable seats and of course, a bit more expensive.
