How Many Seats on an Airbus A321?
The A321 is the stretched A320 — now the dominant narrow-body on US domestic routes. Seat counts range from 159 (JetBlue Mint) to 230 (Frontier dense config).
| Airline | Seats | Notes |
|---|---|---|
| American Airlines | ~181 | A321-200, replacing 757s |
| JetBlue (Mint) | 159 | 24 Mint lie-flat + 135 economy |
| Frontier | ~230 | High-density, no first class |
The A321 uses the same 3-3 single-aisle layout as the A320 — just with more rows. The A321neo is 20% more fuel efficient than the A321-200.
