For long-haul a/c, it seems that a 4-class plane is the trend:
First with twin-size beds and a jacuzzi (ok, not really, but...) (1-2-1)
Business with flat beds (2-2-2)
"Status Coach" with 2-4-2 19" seats, 35" pitch
"Fare War" with 3-3-3 18" seats, 31" pitch
I'm woefully lacking in knowledge of the non-US carriers. I know that BA has 4-class, and seem to remember seeing something like it on Eva. VS has 3-class, with Upper Class doing F/J.
Is there a trend outside the US to split coach like this?
