Updated Assumptions for All-Business (Non-Lie-Flat) Layout
- Seat Type: Recliner or cradle business seats (not lie-flat)
- Seat Pitch: 38–42 inches (~96–107 cm)
- Seat Width: ~21–22 inches (~53–56 cm)
- Configuration:
- Main deck: 2-2-2-2 = 8 seats per row
- Upper deck: 2-2 = 4 seats per row
Revised Layout Estimate
Main Deck (usable cabin length: ~50 m = ~164 ft)
- At 38″ pitch → ~33–34 rows possible
- 8 seats per row → 33 rows × 8 = 264 seats
Upper Deck (usable cabin length: ~25.6 m = ~84 ft)
- At same pitch (~38″) → ~14 rows possible
- 4 seats per row → 14 × 4 = 56 seats
Total Seat Count: All-Business Recliner Layout
| Deck | Rows | Seats per row | Total Seats |
| Main deck | 33–34 | 8 | 264–272 |
| Upper deck | 14 | 4 | 56 |
| Total | — | — | ~320–328 |
328 all-business seats is a realistic upper limit with recliner-style seating and smart cabin planning. You might reduce this slightly to accommodate lavatories, galleys, and crew rest.
Updated Weight Estimate
| Configuration | Seats | Approx. Cabin Weight |
| Standard 3-class | ~416 | ~24–25 t |
| High-density Economy | ~524 | ~26–27 t |
| All-Business (328) | 328 | ~22–23 t |
- Business seats are heavier per unit, but fewer are installed.
- Galley, seat electronics, and in-seat power also factor in, but total cabin weight is still 1–3 t lower than high-density Y-class.
Summary
- Seating capacity: ~320–328 business recliner seats
- Cabin layout: Main deck 2-2-2-2, Upper deck 2-2
- Weight: ~22–23 tonnes cabin fit (vs. 25–27 t typical)
- Excellent comfort + payload balance
- Huge belly cargo potential remains intact due to lower total pax count
