Quick answer: Exit rows (often ~row 21) — up to ~34 in of legroom. Forward Economy rows — quieter, served first, faster off. Avoid: Row just before the exit row — no recline. Typical exit rows: 21 & 22. (United typical 3-3 config — exact rows vary.)

✅ Best seats
  • Exit rows (often ~row 21) — up to ~34 in of legroom.
  • Forward Economy rows — quieter, served first, faster off.
  • Over-wing seats for the smoothest ride.
⛔ Avoid
  • Row just before the exit row — no recline.
  • Last 3–4 rows — no recline, near the galley/lav.
  • Bulkhead rows near the forward lav on some configs.
Good to know
  • Longer than the MAX 8 — extra rows make the tail a longer walk.
  • Larger 'Space Bins' vs older 737s; same 6-abreast cabin width as all 737s.
