Best-seats guide · Boeing 737-900ER
The best seats on the Alaska Airlines Boeing 737-900ER.
The Alaska Airlines Boeing 737-900ER seats 178 passengers across 2 cabins. Every row below is rated on legroom, location and distance from galleys and lavatories.
Alaska Airlines' 737-900ER is the longest conventional 737 in the fleet, carrying the same two-cabin structure — two-two First, three-three Economy — as the newer MAX 9. It is used on longer domestic sectors and some transcontinental routes. Exit rows and extra-legroom rows within Economy are the picks to target.
The extended fuselage means a particularly deep Economy cabin: the rear rows sit a long walk from the front exits, and on a transcontinental sector that distance adds up at both ends of the flight. The front rows of Economy are the cleaner choice for a quick exit; the exit rows in the middle are still the legroom standout. First is the consistent two-two domestic recliner across all of Alaska's long narrow-body flying.

Both carry the same cabin layout — two-two First and three-three Economy with similar seat counts. The MAX 9 is the newer, more fuel-efficient aircraft; the 900ER is the earlier generation. Seat products and legroom structure are comparable between the two.
The exit rows carry the most legroom in Economy, followed by the extra-legroom designated rows. On a longer domestic sector these rows are the practical first step before considering an upgrade to First.
On the longer 737-900ER, the rear of the cabin sits further from the front exits and close to the galley. For a transcontinental flight, a forward seat in Economy or an exit row mid-cabin is the more settled option.
