The Economy cabin offers a mostly 3-3-3 (A,B,C - D,E,G - H,J,K) arrangement, with rows 31 to 35 immediately after the Business cabin, followed by rows 36 to 48 and then 49-61 in the back section.
Row 31 is a bulkhead row but note that it has no window. Row 36 is an exit row but also has no window. Note that the door impinges on the legroom of the seat nearest to it on both sides. Further back, row 44 is also window-less.
At the back, rows 60 and 61 are configured 2-3-2.
