No, thats right! The 777-300 ER's have got 4 configs! The first lot of 2 class aircraft that came were 42 in J and 385 in Y, now they seem to be (with the new seating) 42 J and 400 in Y.
The three class aircraft when they first arrived had no crew rest and were a config of 12/42/310. Now the newer ones (with the beds in J and the crew rest compartment) are configured to 12/42/304.
Hope this clears things up a little for you!
