How Many Seats on a Boeing 777?
The Boeing 777 family spans three main variants. The 777-300ER is most common on long-haul routes — often with a dense 3-4-3 economy layout.
| Variant | Typical seats | Economy layout |
|---|---|---|
| 777-200ER | 306 | 3-3-3 (9 abreast) |
| 777-300ER | 396 | 3-4-3 (10 abreast) — dense |
| 777X (777-9) | 384 | 3-4-3 (10 abreast) |
The 3-4-3 layout on the 777-300ER squeezes seats to ~17 inches — the Boeing 777 fuselage was designed for 9-abreast. Window seats in the 3-seat sections are best.
