The Boeing 717 interior presents a fascinating study in regional jet design, carrying the direct genetic lineage of the legendary Douglas DC-9. While modern single-aisle cabins favor wide-body style curves and massive overhead bins, the 717 maintains a tight, specialized footprint optimized for high-frequency short-haul routes. Operating primarily with carriers like Delta Air Lines and Hawaiian Airlines, this compact twinjet accommodates between 106 and 117 passengers depending on the airline's configuration.
Understanding the 717 interior requires looking beyond standard marketing descriptions to examine how its unique five-across seating arrangement, rear-mounted engines, and narrow fuselage shape influence actual passenger comfort. Whether you're booking an inter-island hop or a regional connection, knowing how this cabin functions helps you pick the right seat and manage your expectations for legacy regional flying.
The Origins of the 717 Cabin Layout
The story of the Boeing 717 interior actually starts with McDonnell Douglas and the design of the MD-95. Conceived in the early 1990s as a direct replacement for aging first-generation DC-9s, the aircraft was meant to capture the 100-seat market with high efficiency and updated flight decks. When Boeing acquired McDonnell Douglas in 1997, the jet was rebranded as the Boeing 717, but the physical cabin architecture remained deeply rooted in the Douglas heritage.
The fuselage cross-section retains the classic narrow profile of the DC-9 and MD-80 series. With an exterior fuselage width of 11 feet 1 inch and an interior cabin width of 10 feet 4 inches, the aircraft simply didn't have the floor space to support modern six-across economy seating without making the seats unlivable. Engineers settled on a distinct layout that defines the entire passenger experience.
- Cabin Length: 76 feet 11 inches of usable passenger space.
- Cabin Height: 6 feet 8 inches, offering adequate headroom for most travelers.
- Seating Arrangement: 2+3 layout in economy, creating a unique asymmetric feel.
Decoding the Five-Across Economy Experience
The defining characteristic of the 717 interior is the 2+3 economy seating configuration. On the left side of the single aisle, passengers find pairs of seats (A and C). On the right side, groups of three seats (D, E, and F) occupy the row. This asymmetry creates an immediate design puzzle for couples traveling together and solo fliers trying to avoid middle seats.
Seat width in standard economy measures roughly 18.1 inches, which feels surprisingly tolerable compared to some modern high-density narrowbodies, but pitch varies significantly by carrier. Airlines like Delta configure their 717 cabins with three distinct service tiers: a 2+2 First Class cabin upfront, followed by a dedicated extra-legroom section, and standard main cabin seating in the rear.
- First Class (2+2 Layout): Offers a generous 37-inch pitch and 19.6-inch width with traditional recliner seats.
- Delta Comfort+ (2+3 Layout): Retains standard seat width but increases pitch to 33 inches for extra legroom.
- Main Cabin (2+3 Layout): Standard economy seating featuring a tighter pitch of 30 to 31 inches.
Acoustic Realities and Engine Placement
One cannot discuss the Boeing 717 interior without addressing the two Rolls-Royce BR715 turbofan engines mounted directly to the rear fuselage. This legacy design choice mimics the DC-9 and Caravelle layouts of decades past. While rear-mounted engines leave the wings remarkably clean and aerodynamically efficient for short-field operations, they dramatically impact cabin acoustics.
Forward of the wing, the 717 cabin is remarkably quiet. Passengers seated in first class or the front rows experience minimal engine drone, making it comparable to much newer aircraft. However, as you move toward the back of the aircraft, particularly past row 18, the acoustic environment changes entirely. The proximity to the engine exhaust and high-pressure turbines creates a noticeable roar during takeoff and climb, tapering off to a steady hum at cruising altitude.
- Quietest Zone: Rows 1 through 5, including First Class and premium economy sections.
- Moderate Zone: Rows 6 through 15 over the wing and mid-cabin.
- Noisiest Zone: Rows 16 through 21 near the rear galley and lavatories.
Overhead Storage and Galley Constraints
Because the 717 was designed in an era before every passenger boarded with a heavy roller bag, its overhead storage bins are noticeably smaller than those found on modern Boeing 737 MAX or Airbus A320neo aircraft. Passengers flying on full 717 flights frequently encounter gate-check requests for standard carry-on suitcases because the older bin geometry simply cannot accommodate modern bag depths when loaded flat.
Galley and lavatory placement also reflects the compact nature of the airframe. On most configurations, primary lavatories are clustered at the extreme rear of the aircraft near the engines, creating a high-traffic bottleneck during descent. Flight attendants manage meal and beverage service from compact forward and aft galleys, relying on streamlined cart configurations designed specifically for the narrow aisle.
Common Passenger Mistakes on the Boeing 717
Travelers frequently make specific errors when selecting seats or preparing for a flight on this specific regional jet. Avoiding these pitfalls ensures a much smoother journey.
- Booking the Last Row: Selecting seats in the final row puts you directly next to the lavatories and engines, resulting in high noise levels and heavy foot traffic throughout the flight.
- Assuming Standard Overhead Space: Packing oversized carry-on luggage without checking dimensions often leads to mandatory gate-checking because the 717 bins cannot handle deep bags.
- Ignoring the Right-Side Asymmetry: Solo travelers who despise middle seats should carefully verify whether they are picking a window seat on the two-seat left side versus the three-seat right side.
Frequently Asked Questions
Does the Boeing 717 have personal seatback entertainment screens?
Original factory 717 interiors did not include embedded inflight entertainment screens. Most operating airlines provide wireless streaming entertainment accessible via personal smartphones, tablets, or laptops connected to onboard Wi-Fi.
Are there power outlets available at every seat?
Power availability depends entirely on the operating carrier. Major operators like Delta have retrofitted their 717 fleets with AC power outlets and USB ports installed beneath or between the seats, though older configurations may lack power access in the rear main cabin.
Why does the Boeing 717 have engines on the tail?
The rear-mounted engine design is inherited directly from the Douglas DC-9 lineage. This configuration keeps the wings clean of heavy engine pylons, improving short-field performance and aerodynamic efficiency on short, multi-leg regional routes.
How loud is the back of a Boeing 717 cabin?
The rear rows are notably louder than the front due to the proximity of the dual Rolls-Royce turbofans. Passengers sensitive to engine noise should select seats forward of the wing to ensure a quiet flight experience.
