So they are now calling 'economy comfort' a separate class, sounds like a marketing thing.

I've sat in those seats when deadheadding, they are the exact same coach seats that everyone behind you is sitting in, with no additional meal or drink service, same as coach. I guess if you have really long legs, you'd pay extra for that, but otherwise, I see little difference than all the other coach seats.

But then some people stand in a long line for a $5 cup of coffee too.
