Overview of Southwest Airline Seating
Southwest Airlines configures its mainline fleet with a single-class cabin layout, using a 2 2 seating arrangement without middle seats. This design aims to streamline boarding and improve aisle flow. Seat dimensions and pitch vary across aircraft types, and understanding these factors is essential for estimating personal comfort on longer flights.
Mainline Aircraft Seat Specifications
Boeing 737 Series (737-700, 737-800, 737 MAX variants)
The 737 family forms the core of Southwest’s narrow-body fleet. While seat widths can differ slightly by door and row, typical seat dimensions emphasize maximizing capacity while meeting (U.S.) regulatory standards for seat width and pitch. These aircraft prioritize high utilization and frequent short-to-medium-haul routes.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Seat Width (approximate) | About 17 to 17.5 inches per seat (side to side) | Manufacturer spec / Southwest config |
| Seat Pitch (typical) | 30 to 31 inches in many rows; some rows vary | Southwest config tables / seat maps |
| Configuration | 2 2 (no middle seats) | Southwest fleet documentation |
| Aisle Access | Single aisle between seats | Southwest seat map layout |
Boeing 717 Aircraft
Used on select short- to medium-haul routes, the 717 typically offers a slightly roomier feel due to its smaller cabin cross-section and layout, though seat width remains in a similar range. The 2 2 configuration is also standard, and the lower passenger volume can mean fewer overhead bins competing for space.
Embraer Regional Jets (E170, E175, E180, E190)
On regional routes, Southwest operates select Embraer aircraft. Seat dimensions on these smaller jets tend to be close to mainline values, but the reduced cabin width can make the cabin feel more compact. Pitch and width can differ noticeably between forward and rear sections of these planes.
Key Definitions: Seat Size Terms
Seat size in commercial aviation is usually described using two primary measures: seat width and seat pitch. Width refers to the distance between armrests side to side. Pitch refers to the distance from one seatback to the next seatback in the same row, which affects legroom. Understanding these terms helps travelers compare options and anticipate comfort on different aircraft.
Comparing Southwest to Competitors
Southwest’s single-class 2 2 layout influences how its seats compare with competitors that use multiple cabins or 3 3 configurations on similar aircraft. While exact numbers vary by plane and row, the absence of middle seats can make the perceived width more generous. Travelers often note easier boarding and deplaning, which affects the overall experience independent of seat dimensions.
- 2 2 layout removes middle seats, simplifying aisle movement.
- Seat pitch commonly aligns with or slightly below mainline averages for the same aircraft type.
- Width is designed to meet U.S. standards while maximizing capacity.
Comfort Factors Beyond Dimensions
Dimensions are important, but comfort also depends on cabin pressure, humidity, overhead bin space, and seat cushion firmness. On longer flights, personal tolerance for seat pitch and the ability to stow carry-on luggage comfortably can influence satisfaction. Selecting a slightly more spacious row during booking or using boarding groups strategically can help improve the experience.
Practical Guidance for Travelers
When choosing seats on Southwest, consider aircraft type, row location, and personal priorities. If legroom is a priority, check seat maps for additional pitch in exit rows or bulkhead areas. For broader shoulders, compare approximate seat widths across rows. Booking early can increase options, especially on flights where certain aircraft types or favorable rows are limited.
Summary and Takeaways
Southwest airline seat size generally offers about 17 to 17.5 inches of width and 30 to 31 inches of pitch on mainline narrow-body aircraft, with variations on regional jets and older planes. The 2 2 seating design enhances flow and reduces middle-seat constraints. Travelers who understand these dimensions and how they vary across aircraft can make informed choices that align with personal comfort preferences on both short and long trips.
