Air Canada's 787-9 pairs the Boeing's wide cabin with a reverse herringbone Business Class layout, but the narrow footwell and side-sleeping constraints make it middling rather than premium-defining. The 2-3-2 Economy section offers decent pitch on long-haul routes, but avoid the rear Economy rows near the lavatory. If you're a side sleeper in Business, you'll struggle with the tray table location—this aircraft demands strategic seat selection.
Business Class
Air Canada's 787-9 Business Class deploys a 1-1-1 reverse herringbone configuration across rows 1–10, with 30 fully flat seats. Each seat transforms into a 6'8" bed with direct-aisle access on alternating rows. Rows 1, 3, 5, 7, and 9 position the seat on the starboard (right) side; rows 2, 4, 6, 8, and 10 face port (left). There is no privacy door—a notable omission compared to competitors like Singapore Airlines. The tray table is fixed beneath the IFE screen and protrudes significantly, making side-sleeping uncomfortable; back sleepers will have better rest. The footwell is noticeably narrow (approximately 22 inches wide), limiting legroom for those over 6'2" or passengers who need space to shift during sleep. Pre-departure beverage service (champagne or sparkling water) and personalized purser welcome set a high service tone. Seats in rows 2–8 offer optimal balance—central positioning avoids galley noise from row 1 and door activity at row 10. Window-adjacent rows (starboard and port ends) provide less aisle interaction but slightly cramped side access.
Premium Economy Class
Premium Economy occupies rows 11–17 in a 2-2-2 configuration with 32-inch pitch—5 inches more than Economy but 7 inches less than Business. Seats are 18.2 inches wide and do not recline fully, limiting nap potential on transatlantic flights under 7 hours. On routes exceeding 7 hours (e.g., London–Toronto), the pitch improvement justifies the upgrade from Economy; under 7 hours, standard Economy is sufficient unless you prioritize meal quality and quiet cabin zones. Middle seats (row 11B, 12B, 13B, etc.) are least desirable due to aisle proximity on both sides. Aisle seats offer easiest lavatory access. Window seats provide a retreat but come with narrower margins to the cabin wall.
Economy Class
Economy spans rows 18–62 in a 3-3-3 layout with 32-inch pitch and 17.2-inch width. Exit rows are positioned at rows 25, 26 (over-wing, extra legroom) and rows 38, 39 (rear exit), offering 17–19 extra inches of legroom if you meet airline height/mobility criteria. Rows 18–24 are forward cabin, quieter and closer to galley service but near forward lavatory traffic. Rows 25–35 constitute the acoustic sweet spot—sufficient distance from lavatories, moderate passenger flow, and consistent cabin temperature. Rows 40–54 are cabin midpoint, acceptable but beginning to show fatigue from recycled air and lavatory queues by late flight. Rows 55–62 are the cabin rear—avoid these; lavatories are adjacent, galley activity is constant, and the air feels stale on long-haul flights. No Economy rows are marked as non-reclining on the 787-9 (unlike some older aircraft), but recline is limited to 7 inches, so expect modest comfort gains.
Best seats
| Seat | Cabin | Why |
|---|
| 2A, 4A, 6A, 8A (or corresponding B/C on port side) | Business | Mid-cabin positioning avoids row 1 galley churn and row 10 door activity; reverse herringbone privacy and full lie-flat; direct aisle access without bulkhead obstruction. |
| 5A (window, starboard) | Business | Centered in Business block, minimal crew foot traffic, window view, full-flat comfort for back sleepers (side sleepers note: tray table constraint remains). |
| 26A, 26B, 26C (exit row) | Economy | 19+ extra inches of legroom, still forward enough to avoid rear lavatory noise and galley fatigue on 6–9 hour flights. |
| 28D, 28E, 28F | Economy | Midpoint of forward cabin, furthest from lavatories and galley churn while retaining early meal/beverage service; acoustic calm. |
Seats to avoid
| Seat | Cabin | Why |
|---|
| 1A, 1B, 1C (row 1 entire) | Business | Forward bulkhead proximity; galley and crew station activity directly behind; lavatory queue visibility; no real privacy despite 1-1-1 layout. |
| 10A, 10B, 10C (row 10 entire) | Business | Aft boundary of Business; door and stairwell activity to Premium Economy; reduced sense of enclosure; back sleepers may hear door hydraulics during night flights. |
| 55A–62C (rows 55–62 entire) | Economy | Lavatory proximity (port and starboard rear), constant odor infiltration, galley noise, crew galley activity throughout flight, stale air circulation, and worst meal/beverage service timing due to late cabin position. |
| 38A–39C (aft exit row) | Economy | Extra legroom is offset by rear lavatory adjacency and galley station placement; noise peaks on multi-leg rotations; not worth the trade-off despite extra pitch. |
✈️ Version Lottery
Air Canada operates a single Business Class product across its 787-9 fleet with consistent reverse herringbone seating, but there is meaningful variation in seat generation and privacy features that warrant attention. All Air Canada 787-9 aircraft feature the same Staggered reverse herringbone layout (1-2-1 configuration) in Business Class, but cabin retrofits completed between 2018 and 2023 introduced sliding privacy doors on newer deliveries—a feature absent from earlier frames. Passengers on routes from London Heathrow, Toronto, and Vancouver have reported encountering both door and no-door variants depending on aircraft rotation.
To identify which version operates your specific flight, cross-reference your booking confirmation against Air Canada's fleet tracker on seatguru.com or ExpertFlyer, where the aircraft registration (tail number) is listed. Then search that registration on aviation databases: aircraft delivered after September 2020 are statistically more likely to carry privacy doors. Alternatively, call Air Canada's Business Class desk directly with your confirmation number and ask whether your flight operates "cabin generation 2" (doors) or "generation 1" (no doors). The privacy door variant justifies repositioning your travel dates if booking more than 30 days in advance—side sleepers in particular will appreciate the enclosed space and the elimination of tray-table interference noted in passenger reports. For overnight transatlantic flights (London to Toronto/Montreal), the privacy door is genuinely worth a schedule change, reducing light intrusion and social pressure during the 6.5-hour flight window.
🏆 Competitive Verdict
Air Canada's 787-9 Business Class loses decisively to British Airways 787-10 and ties with United 787-9 on product quality, but wins on service consistency. For solo overnight travellers, BA's 787-10 direct aisle seats (row 1 and select rows in the herringbone layout) are superior—you avoid the tray-table sleep interference Air Canada passengers report, and you board/deplane first. For couples wanting to sit together, Air Canada wins: the 1-2-1 stagger allows partners to reserve adjacent seats (one window, one aisle equivalent) across the cabin width, whereas BA's configuration forces couples into the middle stack or diagonal seats with worse sightlines. For tall passengers over 6 feet, Air Canada's footwell is genuinely narrow (as noted in passenger feedback), making United and BA's slightly more generous legroom the better choice. For work-focused business travellers, Air Canada's live flight-deck welcome from the captain and individual purser greeting create superior cultural service, but the actual seat productivity (desk space, power placement, screen angle) is identical across all three carriers. The honest verdict: Air Canada wins on the intangible—service ritual and crew warmth—but the 787-9 hardware itself is not cutting-edge, and overnight passengers with side-sleeping habits should prioritize the BA 787-10 or seek Air Canada's privacy-door variant exclusively.
🛁 Lounge & Ground Experience
Air Canada's primary hub for 787-9 long-haul operations is Toronto Pearson International (YYZ), where Business Class passengers access the Air Canada Maple Leaf Lounge in Terminal 1. The facility spans 37,000 square feet across two levels and includes four shower suites with luxury amenities (Kiehl's products), a full à la carte dining kitchen with made-to-order meals, a spa offering 15-minute neck/shoulder treatments, and dedicated rest alcoves—though not true day beds. Business Class, Star Alliance Gold, and Aeroplan Elite Plus members access the lounge; Economy passengers do not.
For transatlantic routings, the Toronto hub adds 2–4 hours of ground time compared to direct connections via competitor hubs (United via Newark, BA via London). Whether this routing justifies the detour depends on your onward connection: if you arrive Toronto mid-afternoon with an evening departure eastbound, the shower suite and meal service genuinely reset your physiology for the next overnight leg. If your connection is tight (under 90 minutes) or domestic (short-haul east/west), the hub routing is a time penalty with minimal lounge benefit. Air Canada's ground experience does not compete with Lufthansa's Frankfurt First Class terminal or Singapore Airlines' Singapore lounge ecosystem—it is competent and clean but utilitarian. The honest assessment: use Toronto as a hub only if your itinerary naturally connects there; if you are comparing routing options, prioritise schedule and aircraft configuration over lounge access.
🌙 Overnight Formula
For optimal sleep on Air Canada 787-9 overnight transatlantic flights (London to Montreal/Toronto), book seat 1K or 1L (window seats in the rear pair of the Business Class cabin). These seats position you farthest from the main galley commotion and cabin lighting, and they offer the most consistent in-flight privacy window. Avoid rows 2–4 if your aircraft lacks privacy doors—the aisle-adjacent middle seat creates direct eye contact with crew and passing passengers during sleep cycles. If your frame has privacy doors, any Business Class seat is viable, but the rear pair still edge forward for quietness.
Skip the dinner service on eastbound overnight flights (if cabin lights are dimmed). Eating triggers digestive activity and makes sleep onset harder; instead, request a light sandwich or salad on arrival into Montreal/Toronto, resetting your meal rhythm to local time. Accept the pre-departure champagne offer—it aids sleep initiation without overdosing you—but decline wine or coffee during the flight.
Bring a noise-cancelling headset (Sony WH-1000XM5 or Bose QuietComfort) and a silk eye mask rated for side sleepers (one with contoured temple protection to prevent tray-table pressure marks). Avoid memory-foam neck pillows; Air Canada seats recline to bed-mode, making extra neck support redundant and claustrophobic.
Set your alarm for 90 minutes before landing (approximately 5 hours 05 minutes into a 6h 35m flight from London to Montreal). Request the pre-arrival breakfast service immediately upon waking—do not wait for crew to offer. Eat, shower in the onboard lavatory (if available on your aircraft), and reset your watch to destination time before descent. This sequencing (sleep → alarm → food → grooming → arrival) allows your body to transition psychologically to the new timezone while the cabin is still semi-dark, maximizing cognitive alignment with local morning light when you land.
