The business class cabins are actually different, and Emirates also has 3-class 330's whereas Sri Lankan does not. EK's 2-class 330's have 4 rows of 2x3x2 seating in business(except for row 1 which is 2x2x2). UL's 330s only have 2 rows of 2x2x2. The economy sections are the same with a 2x4x2 layout.
