Cathay Pacific A340 Seat Guide (2026)

Quick specs

Business Class (Rows 1 - 14)

Cathay Pacific's Business Class is arranged in a 1-2-1 configuration with direct aisle access from every seat, providing maximum privacy for couples and solo travelers alike. All 68 seats convert to fully lie-flat beds measuring 78 inches, making the A340 ideal for transpacific and Europe routes. Rows 2 - 8 (both A and K positions) are the acoustic and privacy leaders - far enough from the flight deck galley (row 1) and the Premium Economy bulkhead (row 15). Rows 11 - 14 sit closer to the midcabin galley and stairwell, introducing minor service noise and occasional foot traffic from cabin crew accessing upper and lower decks. Row 1 (A and K only) offers prestige but proximity to the flight crew rest area and galley chatter. Door closure is immediate and effective on all seats, but window-adjacent positions (A and K) are universally preferred for the sense of enclosure and the ability to manage window shades independently.

Premium Economy Class (Rows 15 - 22)

Premium Economy spans 52 seats in a 2-4-2 layout across 8 rows, positioned between Business Class (row 14) and the main Economy cabin (row 45). Pitch is a genuine 38 inches, a 7-inch gain over Economy, making this cabin the best value for ultra-long-haul flights over 12 hours. Rows 15 - 16 sit directly behind the Business bulkhead, offering marginally extra legroom but modest service delays due to crew transitions. Rows 17 - 22 are the acoustic and convenience sweet spot - far enough from Business turnover and early enough in the aircraft to see faster meal service and lavatory queue avoidance. Aisle seats (C and D in the center block, A and K on the wings) offer easy lavatory access; center-block window seats (C and H for rows with 2-4-2 layout) provide good privacy. Row 22, the final Premium Economy row, is slightly noisier due to proximity to the forward Economy galley and lavatory cluster, but still markedly quieter than main deck Economy.

Economy Class (Rows 45 - 80)

Economy is the A340's Achilles' heel: 215 passengers crushed into a 3-3-3 layout over 36 rows at a miserly 31-inch pitch - barely above budget-airline standards. Rows 45 - 50 (the forward Economy cabin) are the only tolerable zone: quieter, faster meal service, and shorter lavatory queues. Exit rows 50 (over-wing) and 60 - 61 (rear emergency exits) offer 36 - 37-inch pitch but sacrifice reclline and are directly adjacent to lavatories. Rows 60 - 63 are the unqualified disaster zone - positioned directly over the rear galley and lavatories, guaranteeing constant foot traffic, door slamming, and service noise for 14+ hours. Rows 70 - 80 are the absolute rear, where turbulence amplification and the final galley location make sleep nearly impossible. Window seats (A, F, J) throughout rows 45 - 59 are non-negotiable; middle seats (B, C, G, H) should only be accepted with an aisle-seat companion swap. Rows 52 - 59 represent a brief acoustic dip before the rear-galley hellscape begins.

Premium Economy

Cathay Pacific's Premium Economy cabin on the A340 spans rows 32 - 39 in a 2 - 3 - 2 layout, offering 52 seats across the aircraft's width. Seat pitch measures 38 inches, a marked improvement over Economy's 31 inches, and each seat reclines to a near-flat 6 feet 6 inches. The cabin features a dedicated forward galley at row 31, ensuring meal and beverage service reaches Premium Economy passengers before the main cabin queue forms - a meaningful advantage on ultra-long-haul routes where timing affects rest quality.

Meal service in Premium Economy is materially superior to Economy. You receive a full multi-course service with wine and spirits included, plated rather than boxed, and the crew prioritizes your cabin first on most sectors. Cathay Pacific's catering is notably generous; breakfast includes smoked salmon and fresh pastries rather than reheated continental trays.

Lounge access depends on your fare class and frequent-flyer status. Premium Economy passengers do not have automatic lounge access unless holding Diamond or Platinum status in Cathay's Asia Miles scheme, or booking a premium Economy fare marketed as "Premium Economy Plus" (not standard on all A340 bookings). If you hold elite status, you access the Cathay Pacific First and Business Class Lounge at your departure airport.

Best rows in Premium Economy: Row 32 (window seats 32A/L) offers the forward bulkhead position with maximum legroom and quietest cabin feel, though the galley immediately behind can generate minor noise during service. Rows 35 - 38 in the center block (seats B, C, J, K) balance privacy with direct aisle access on a 2 - 3 - 2 layout - no middle-seat squeeze. Avoid row 39, the rearmost Premium Economy row: it abuts the Economy cabin and lacks the psychological separation that justifies the price premium.

✈️ Version Lottery

Cathay Pacific operates two distinct A340 variants in active long-haul service: the A340-300 (16 aircraft) and the newer A340-600 (7 aircraft). The cabins differ substantially in both comfort and configuration.

A340-300: The older variant carries 312 passengers in a three-cabin layout (Business, Premium Economy, Economy). Business Class spans rows 1 - 8 in a 1 - 2 - 1 herringbone, older-generation direct-aisle seats with sliding doors. Premium Economy runs rows 32 - 39. The Economy cabin is split front (rows 40 - 54) and rear (rows 55 - 70), with narrower aisles in the rear section. Pitch and width are standard A340 specifications.

A340-600: The stretched variant accommodates 380 passengers with a four-cabin layout that includes a dedicated upper-deck Business mini-cabin (rows 1 - 8 on main deck, rows 1 - 10 on upper deck). This version features Cathay's latest suites with sliding doors and aisle access in Business Class - a generational leap in privacy. Premium Economy (rows 32 - 39 on main deck) and Economy layouts remain similar to the A340-300, but the upper-deck Business option means fewer main-deck Business rows competing for galley resources.

How to identify your aircraft: On your Cathay Pacific booking confirmation, the aircraft code appears as "A343" (A340-300) or "A346" (A340-600). Alternatively, use ExpertFlyer or FlightAware to search your flight number; the equipment line shows the variant. The Cathay Pacific website seat map also provides visual confirmation: A340-600 displays an upper-deck cabin image, A340-300 does not.

Is it worth changing flights to secure the superior version? Yes, if you hold a Business or Premium Economy ticket. The A340-600's main-deck Business seats are objectively superior - the suites on the upper deck reduce crowding and cabin noise during meals. Premium Economy comfort is nearly identical between variants, so Economy and Premium Economy passengers see minimal practical benefit. Economy travelers should not change flights for the aircraft type alone. If you are booking Business Class on a Hong Kong - London or Hong Kong - New York route, check ExpertFlyer: if the A340-300 is scheduled, request a rebooking on the next A340-600 departure (usually 1 - 2 days later) or consider the newer Boeing 777-300ER as an alternative if it offers better Business Class positioning.

🏆 Competitive Verdict

On long-haul Asia - Europe and Asia - North America routes, Cathay Pacific A340 competes directly with airlines such as Singapore Airlines A380, Emirates A380, and British Airways 747. Verdict: Cathay Pacific A340 wins for solo overnight travelers and loses for couples and tall passengers. The A340's Business Class direct-aisle herringbone seats (A340-300) offer genuine privacy and a lie-flat bed optimized for individual sleep; the cabin is quieter than the A380's sprawling upper deck, and Cathay's crew service is attentive without the chaos of larger aircraft. However, couples holding hands across seat dividers will find the herringbone configuration awkward; the Emirates A380 suite design and British Airways flat-bed club layout allow couples to sit genuinely together. For tall passengers over 6 feet, the A340 pitches 32 - 33 inches in Premium Economy and 31 inches in Economy - the same as competitors - but the A380's enclosed suites in First offer more headroom and a sense of space that the A340 cannot replicate in Business. Work-focused business travelers should choose the A340-600 if available, because the upper-deck Business option and newer suites reduce email queue anxiety and offer genuine flat-bed workspace; the older A340-300's Business cabin feels cramped by 2024 standards, and you will resent the lack of direct aisle access if flying overnight and not sleeping.

🛁 Lounge & Ground Experience

Cathay Pacific operates the Cathay Pacific First and Business Class Lounge at Hong Kong International Airport (HKG), its primary hub for A340 long-haul services. This is the airline's flagship lounge, spanning 47,000 square feet across two levels.

Key facilities: The lounge features eight dedicated shower suites with premium toiletries and a rest area with day beds for rest between connections. À la carte dining is served in a dedicated restaurant zone (not buffet-only); you can order noodles, dim sum, or Western mains prepared to order. A spa offers 15-minute neck and shoulder massage, perfect for pre-flight tension relief. The wine selection includes Champagne and aged Bordeaux. Premium seating zones are split by cabin class; Business Class guests access the main floor, while First Class has a separate upper-deck seating area with quieter ambiance and personalized service.

Access: Cathay Pacific Business Class passengers have automatic lounge access on all international flights. Premium Economy passengers do not have lounge access unless holding Diamond or Platinum status in Asia Miles or booking a premium Economy Plus fare. Economy passengers must hold Platinum status or higher to gain access.

Honest assessment: The HKG lounge experience is excellent and justifies routing via Hong Kong if you hold Business Class or elite status. The shower suites alone provide significant comfort advantage on overnight flights, and the à la carte dining and spa elevate the pre-flight experience beyond competitor hubs (Singapore Airlines Krisflyer lounge, Emirates Concourse lounge). However, if you are Economy class without status, or Premium Economy without Platinum status, routing via Hong Kong adds 2 - 4 hours of connection time with no lounge benefit - in this case, a
