SWISS A340 Seat Guide (2026) | Cabin
TL;DR
SWISS A340 carries approximately 236–246 passengers in a three-cabin layout: Business (40 seats, 1-2-1 fully lie-flat), Premium Economy (48 seats, 2-3-2 at 38" pitch), and Economy (148–158 seats, 3-3-3 at 31" pitch). Best seat overall is 21A or 21K (Business Class window suites with direct aisle access and no middle seat interference). Worst seat is 81K (last row, no recline, galley noise). Surprising insight: SWISS A340 Premium Economy offers genuine middle-seat advantage — the three-abreast layout means window pairs have no trapped middle, and the 38" pitch is competitive with newer A350 Premium.
SWISS operates the A340 on long-haul routes to the Americas and Asia, with a mixed-class cabin split across Business, Premium Economy, and Economy. Row 81 is the last Economy row and sits directly over the rear galley — avoid it unless you enjoy lavatory traffic and zero recline. The A340 is a four-engine workhorse, older than the A350 but still profitable on fuel-efficient thin routes, with less space per seat than newer widebodies.
Quick specs
Cabin | Layout | Seats | Pitch | Width | IFE |
|---|---|---|---|---|---|
Business | 1-2-1 staggered | 40 (rows 1–14) | 6'8" (80") lie-flat | 6'6" (enclosed suites) | Personal 15" HD screen |
Premium Economy | 2-3-2 | 48 (rows 15–23) | 38" | 17.5" per seat (middle) | Personal 10" touchscreen |
Economy | 3-3-3 | 148–158 (rows 24–81) | 31" | 17.2" per seat | Personal 9" screen |
Business Class
SWISS Business on A340 is a 1-2-1 staggered configuration across 40 seats in rows 1–14. Each suite is fully enclosed with a closing door, high privacy walls, and direct aisle access on the odd side (A/D seats). The even sides (B/E in row pairs) are open to the cabin but enjoy wider legroom. All seats convert to flat beds 80 inches long — ideal for transatlantic and Asia routes exceeding 10 hours. Rows 1–7 sit forward of the wing; rows 8–14 are aft. The forward cabin has shorter walk distances to galley and lavatory. Row 14 (last Business) sits directly above the Premium Economy bulkhead — avoid 14B and 14E if you dislike lavatory proximity. Best rows are 2–6 and 9–12: they're far enough from galleys and lavatories, and offer even lighting without being cramped against the cockpit bulkhead (row 1) or the cabin transition (row 14).
Premium Economy Class
Premium Economy spans rows 15–23 in a 2-3-2 layout with 48 seats total. Pitch is 38 inches — genuinely competitive with A350 Premium Economy and superior to most 777 variants. The critical advantage: window pairs (A/C and H/K) have only two seats, meaning couples enjoy no middle-seat penalty. The three-abreast block (D/E/G) is tighter for solo travelers, but aisles are wide and recline is generous (~8 inches). Rows 15–16 are bulkhead; rows 17–22 are standard; row 23 is the final Premium Economy row with curtain separation from Economy below. Rows 15–16 offer extra legroom but lack under-seat storage (bags must go overhead). Best rows for couples are 17–22 in window pairs (A/C or H/K). Avoid row 23 if you dislike being directly adjacent to the Economy cabin and potential lavatory noise from the row below.
Economy Class
Economy runs rows 24–81 in a 3-3-3 layout with 148–158 seats and 31-inch pitch — tight for long-haul but standard for SWISS wide-body economy on older aircraft. Exit row seats with extra legroom are located at rows 43–44 (wing-bulkhead exits) and rows 63–64 (rear-cabin exits). These rows offer 38–40 inches of pitch and no seat in front, making them excellent for passengers over 6 feet or families needing space. Rows 63–64 are preferred: further aft, less engine noise, and quieter cabin traffic. Row 81 is the last row and sits directly over the rear galley — no recline, constant lavatory odor, and cart activity from below. Rows 79–80 are nearly as bad. Rows 75–78 are the true rear acoustic sweet spot: aft enough to escape forward cabin noise, far enough forward to avoid galley churn. Rows 24–25 are the first Economy rows and prone to Premium Economy spillover noise and crew movement. Best Economy seats for long-haul comfort are 43A, 43K, 63A, or 63K (exit row windows). Avoid 80–81 entirely unless it's your only option and the fare is dramatically cheaper.
Best seats
Seat | Cabin | Why |
|---|---|---|
21A or 21K | Business | Mid-cabin window suite with direct aisle access, enclosed privacy door, lie-flat bed, no galley or lavatory proximity. Premium location in the aft Business section. |
9D or 9E | Business | Forward-aft Business pair with optimal wing positioning (quieter than row 1 but ahead of galley noise). Slightly less privacy but excellent for couples. |
18A or 18K | Premium Economy | Window pair with 2-seat layout only — no middle-seat trap. Standard pitch of 38", excellent recline, forward enough to avoid Economy curtain proximity. |
20D, 20E, or 20G | Premium Economy | Centre block with full aisle access and no recline interference. Mid-cabin quiet zone, no bulkhead, no aft lavatory noise. |
63A or 63K | Economy | Rear-cabin exit row window — 38–40" legroom, extra space, aft-cabin quiet acoustic sweet spot, away from galley churn. |
75C or 75H | Economy | Aft Economy acoustic sweet spot — quiet cabin traffic, away from galley, away from lavatory proximity. Standard pitch but maximized comfort on long-haul. |
Seats to avoid
Seat | Cabin | Why |
|---|---|---|
14B or 14E | Business | Last Business row, directly above Premium Economy bulkhead and lavatory. Lavatory odor and traffic seep upward; no recline comfort. |
1A, 1D (row 1) | Business | Cockpit bulkhead — zero under-seat storage, cramped knee room despite bulkhead claims, crew activity from galley immediately aft. |
23A, 23C, 23H, 23K | Premium Economy | Last Premium Economy row — thin seat padding, direct Economy curtain and galley proximity, no privacy, lavatory noise from cabin below. |
24–25 (all) | Economy | First Economy rows directly under Premium Economy curtain — crew spillover, meal-service noise, lavatory odor from above. |
79A–81K | Economy | Last three Economy rows — no recline, galley noise, lavatory traffic, tapered fuselage, no under-seat storage on row 81. |
43B or 43E | Economy | Exit row middles — trapped between two passengers, aisle turbulence, no window views to justify the extra legroom. |
💺 Premium Economy
Configuration & Layout
SWISS A340 Premium Economy occupies rows 12–18, with 52 total seats in a 2-3-2 layout (A/C, D/E/G, H/K). Seat pitch is 38 inches — competitive for long-haul but 1 inch tighter than the newer A350 product. Armrests between the aisles are fixed, but the 2-3-2 configuration means window pairs (A/C and H/K) remain isolated from the three-seat centre block — a genuine benefit for couples and solo travellers seeking privacy.
Dedicated Galley & Service Quality
Premium Economy has a dedicated forward galley (between rows 11 and 12) staffed during meal service, separating you from the Economy cabin queue. Meal service begins 30 minutes after takeoff on most long-haul routes and includes a full hot meal with wine and beer service — noticeably superior to Economy's simplified cart offerings. Cabin crew rotate between cabins, so attention can be inconsistent on fully booked flights. On routes under 8 hours, a light breakfast or snack service replaces the hot meal. Amenity kits are not provided (unlike Business Class), but bedding and a pillow are offered for overnight flights.
Lounge Access & Ground Experience
Premium Economy on SWISS A340 does not grant automatic lounge access. Miles Elite members (Miles & More Gold or Platinum) enter the SWISS Senator Lounge at Zurich (ZRH); others must pay à la carte. At other hubs (London LHR, Paris CDG, Rome FCO), no Premium Economy lounge benefit exists — access is restricted to Business Class and frequent-flyer elites. Boarding occurs in Group 2, after Business and First, ahead of standard Economy (Group 3).
Best Rows — Premium Economy
Seat | Why |
|---|---|
12A, 12C, 12H, 12K | Front row of Premium Economy — bulkhead legroom and priority galley access. Avoid storing bags under the seat (forward bulkhead blocks leg extension). Window pair benefit without the aircraft tail noise. |
A/C and H/K throughout (rows 12–18) | Window pairs only — no middle seat neighbouring you. Quiet location compared to the three-seat block. Wider windows than standard Economy on older A340 variants. |
18H, 18K | Rear window seats in Premium Economy — last row before Economy cabin transition. If you prefer a taller seatback and quieter environment, these hold value; slight galley proximity noise. |
Seats to Avoid — Premium Economy
Seat | Why |
|---|---|
D, E, G (rows 12–18) | Three-seat centre block — middle seat (E) is sandwiched between two passengers. D and G seats face galley-adjacent aisle traffic, particularly during meal service. Avoid E entirely unless travelling as a trio. |
12D, 12E, 12G | Bulkhead row, centre block — zero legroom advantage (bulkhead blocks leg extension), three-seat congestion. |
18D, 18E, 18G | Rear-row centre seats — proximity to Economy cabin noise and cabin crew transition zone; slight reduction in recline due to structural wall behind row 18. |
💻 Digital Nomad Workspace Audit
Tray Table Stability & Laptop Workspace
SWISS A340 tray tables are 6.5 inches wide and 8 inches deep when deployed — adequate for a 13-inch laptop in portrait orientation, marginal for a full 15-inch machine in landscape. The table pivots from the armrest and has moderate flex under typing load; sudden turbulence can shift an open laptop. Premium Economy tables are marginally more robust than Economy due to reinforced armrests. For serious work, a 10–12-inch ultrabook is strongly preferred. Stability improves if you angle the screen back and tuck your elbows inward, but expect some wobble on transatlantic flights during descent turbulence.
WiFi System & Provider
SWISS A340 is equipped with Viasat's SwiftBroadband-Safety system (SBSS), providing satellite-based connectivity across the Atlantic and Europe. The SSID broadcast as "SWISSAIR-WIFI" or "SWISSAIR-WIFI-PREMIUM" (Premium Economy and Business Class receive higher priority bandwidth). Connectivity is operated and billed by SWISS directly; Economy passengers receive 1-hour complimentary access upon login; Premium Economy and Business Class passengers receive unlimited access as a cabin benefit. Ground-based cellular roaming (LTE) only occurs within 200 miles of European coastlines and North American airspace near land.
Real-World Speeds on Typical Routes
Passengers consistently report 0.8–2.5 Mbps download and 0.3–0.6 Mbps upload on Viasat SBSS during Atlantic flights. Transatlantic routes (ZRH–JFK, ZRH–ORD) show the slowest performance due to satellite handoff zones; European routes (ZRH–LHR, ZRH–CDG) achieve 2–3 Mbps. Video streaming is unreliable; email and messaging apps perform acceptably. Speed fluctuates noticeably during polar routing (especially north of 75° latitude), where satellite coverage degrades. Premium Economy and Business users report minimal throttling compared to Economy, but absolute speeds remain satellite-limited. On a 9-hour flight, expect 15–45 minute delays for standard website loads.
Power Outlets by Cabin — Type & Wattage
First Class: AC sockets (110V/60Hz via inverter) rated ~500W per seat, located in the armrest. Dedicated USB-A (2.4A) and USB-C (15W, USB PD) ports integrated into the seat control unit. Reliable for overnight laptop charging.
Business Class: AC socket (110V, ~300W) in the armrest; USB-A (2.1A) and USB-C (18W USB PD) in the seat control panel. Sufficient to charge a modern laptop, though AC outlet quality varies between Suites and open seats.
Premium Economy: USB-A only (2.1A standard, older seats may have 1A). Located in the armrest or seat-back pocket. No AC outlet. Charging a 15-inch laptop via USB is not practical; plan for top-up charging before the flight or use a portable battery pack (20,000 mAh recommended).
Economy: USB-A (1.5–2A) at every seat; mounted in the seat-back pocket in front. AC sockets are not available. Charging is slow on older devices; modern phones reach 50% charge in 4–5 hours.
