Which statement best describes seating on a narrow-body aircraft?

• A. Two Aisles Aircraft
• B. One Aisle Aircraft; 2x2 seating in United Business and 3x3 seating in Economy Plus and general Economy
• C. Three Aisles
• D. No aisles

Answer: (B)

Single-aisle design defines narrow-body seating. The cabin width fits two seats on each side of one central aisle in the more premium block, giving a 2-by-2 layout in United’s business class. In the economy sections—both Economy Plus and general Economy—the width allows three seats on each side of the aisle, resulting in a 3-by-3 arrangement. This contrasts with wide-body aircraft, which use two aisles and often wider multiple-seat blocks. So the description matches the typical narrow-body arrangement you’d expect.
