The Thai Lion Air Boeing 737-900ER carries 215 passengers across Economy only. Every seat is rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 20C, 20D, 21A, 21B, 21C, 21D. Another 12 seats are rated best or good. Look for 18 extra-legroom seats for the most room.
Seats rated avoid on this map are 17A, 17F, 19A, 19B, 19E, 19F. Another 18 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
The -900ER is a stretched, longer version of the 737 that carries more rows and more passengers in the same single-class economy layout. The cabin is denser and deeper, so the rear seats sit further from the front door than they do on the shorter -800.
No. It is all-economy in one six-abreast cabin. The only variation is legroom and position, so the exit rows and bulkhead are the seats to target and the deep rear rows are the ones to avoid.
A forward seat clears the aircraft fastest, and on the longer -900ER that advantage is bigger because the rear rows are so far back. If you have a tight connection, choose a row toward the front of the cabin.
The exit rows over the wing and the bulkhead row have the most legroom on the -900ER. Both usually carry a fee, and the exit rows come with the usual conditions on recline and stowage during take-off and landing.
