All front row seats – AC/DEFG/HK in row 39; ABC/DEFG/HJK in row 43; ABC/HJK in row 59; and DEFG in row 60 – have more legroom, as do seats 40C and 40H due to there being only eight seats in row 39.
You may want to avoid rows 42 and 72, as these are located closest to the lavatory. Seats ABC in rows 56 and 57 are also adjacent to the galley, meaning noise and potential disruption from meal services could be more of a factor.
