The Boeing 777-300ER forms the backbone of Cathay Pacific's long-haul fleet. This highly efficient aircraft serves long-haul routes, primarily to North America, and features Cathay's new range of economy, business and first class products. 

First

Only six seats in rows 1 and 2 (configuration 1-1-1, identified as A-D-K).

Business

Two cabins. The first cabin is just two rows of business class (rows 11 and 12 - configured 1-2-1, identified as A-DG-K). The second cabin has a single seat 15A in the first row, followed by 12 rows (16 to 27).

This aircraft is gradually being installed with the new business class product, which can be seen here.

Economy

Starts with row 30 - though this is only three seats in the centre (DEG) and then rows 31 back to 44. Row 31 is ABC-DEG-HJK with ABC and HJK being extra leg room seats (because of the emergency exit).

The cabin ends with row 44, ABC.

The final cabin of 13 rows (54 to 67). Row 54 is ABC - HJK - all of which are extra leg room seats. The final row is 67 DEG.

The most legroom to be found here is in rows 32 and 55, which are also positioned nearest the exit doors.
