| Row Range | Pitch | Notes |
|---|---|---|
| 7–13 | 32" | Standard front Economy |

3.1 Best Economy Seats

4. A321LR vs A330 – Which Is Better?
| Aircraft | Highlights |
|---|---|
| A321LR | More intimate cabin, faster boarding, same lie-flat Business product, but tighter 3-3 Economy |
| A330-300 | Larger cabin, 2-4-2 Economy better for couples, more lavatories |
On the A321LR, paying for rows 14–15 in Economy is a strong value play to offset the narrower cabin.
