Score your exact flight →Exit rows — usually the most legroom in economy — are rows 20–21 on this layout. Rows 10–15 are sold as extra-legroom seats. The forward rows feel widest; rows toward the tail narrow and often sit near galleys and lavatories.
Window seats sit in a noticeable sidewall recess, so a seat lined up with a window gains a few extra inches of shoulder room. The windows sit low on this aircraft, so taller passengers often lean down to look out. On this Delta Air Lines layout, watch for 11A, 12F — window seats with no window or a misaligned one.
SeatScore scores all three seat types for the Delta Air Lines Boeing 737-900ER. Aisle seats give the most freedom; window seats give a wall to lean on and the added recess; middle seats have the least space. Enter your flight on SeatScore for a seat-by-seat heat map.
