Stretched 737. Roomy window seats up front; the extra length means snugger rows at the back.
Check your exact flight →The Boeing 737-900ER is a narrow-body jet with a cabin about 139 inches wide and economy seats around 17.3 inches across, in a 3-3 layout.
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.
Aisle seats on the Boeing 737-900ER give the most freedom to move and stretch a leg, at the cost of cart and foot traffic. Middle seats have the least personal space. SeatScore scores all three seat types so you can compare them on your specific flight.
The last few rows sit where the fuselage narrows toward the tail and often border galleys and lavatories, so they feel tighter. Exit rows add legroom but sometimes have limited recline. Enter your flight on SeatScore to see every row scored for your airline's exact layout.
