WestJet vs Air Canada 2026: Which Canadian Airline Wins?

Canada’s domestic airline choice comes down to two carriers that started from very different places and have been converging ever since. Air Canada is the flag carrier, a Star Alliance founding member with 160 aircraft serving 222 destinations across 63 countries. WestJet launched in 1996 as Canada’s answer to Southwest Airlines, a low-cost disruptor based in Calgary. Thirty years later, WestJet operates 110 aircraft to 139 destinations, flies 787 Dreamliners to Europe and Asia, and sells lie-flat business class.

The convergence makes this comparison harder to call than it once was. WestJet is no longer just the cheap option, and Air Canada is no longer the only game in town for anything beyond domestic hops. In 2025, WestJet posted better on-time numbers (78.6% vs 73.3%), while Air Canada maintained its clear advantages in network reach and premium cabin products. For pure domestic leisure travel and routes through Western Canada, WestJet is the better default. For international connections, Star Alliance access, and premium cabins, Air Canada wins, and the gap on those fronts is real.

What We Looked For

• On-time reliability, where both Canadian carriers have historically trailed US competitors but made significant gains in 2025
• Carry-on and baggage policies, which are now nearly identical between the two airlines, including the same basic-fare carry-on restriction
• Seat comfort and cabin products, from WestJet’s 28-inch pitch controversy to Air Canada’s Signature Class lie-flat suites
• Route network and hub geography, the clearest structural difference between a 222-destination flag carrier and a 139-destination competitor
• Loyalty programs, comparing WestJet Rewards’ simplicity against Aeroplan’s global flexibility
• Value for money, since WestJet’s low-cost DNA still shows in its pricing even as the product moves upmarket

Which airline charges less for bags, WestJet or Air Canada?

Nearly identical. Both airlines restrict carry-ons on their cheapest fares, charge the same first checked bag fee ($45), and publish similar personal item limits. This category is a tie.

The days when WestJet had a clear baggage advantage over Air Canada are over. Both airlines now strip the carry-on from their lowest fare class on North American routes, and both charge the same baseline fees for checked bags.

Carry-on. WestJet allows 56x23x36 cm (22x9x14 inches). Air Canada allows 55x40x23 cm (21.5x15.5x9 inches). The numbers are formatted differently but describe essentially the same size bag. Neither airline publishes a weight limit, just a requirement that you can lift the bag into the overhead bin unassisted.

Basic fare carry-on restriction. WestJet UltraBasic allows only a personal item on domestic and cross-border flights, with an exception for flights to Europe and Asia where the carry-on is included. Air Canada Economy Basic restricts to a personal item on flights within Canada and to the US, Mexico, Central America, and the Caribbean. Both airlines include the carry-on starting at their second fare tier.

Personal item. WestJet allows 41x33x15 cm (16x13x6 inches). Air Canada allows 43x33x16 cm (17x13x6 inches). Air Canada’s allowance is slightly larger in depth and height, which could matter if you pack a thicker laptop bag.

Checked bags. Both charge $45 for the first checked bag and $60 for the second on domestic and cross-border routes. WestJet’s overweight fees are lower ($88 for 51-70 lb vs Air Canada’s $118), which matters if you tend to overpack. WestJet EconoFlex includes the first bag free. Air Canada Economy Flex includes the first bag free. Same structure.

Seats and comfort

Air Canada has the better premium product. WestJet has been through a turbulent seat pitch saga. In standard economy, the two are close enough that the specific aircraft matters more than the airline.

Economy seat pitch. This is where WestJet stumbled in late 2025. The airline installed ultra-slimline seats at the back of some Boeing 737-800 and 737 MAX 8 aircraft with a 28-inch pitch, the tightest in Canadian aviation. Passenger backlash was immediate and intense. A viral video of the cramped configuration forced WestJet to reverse course in January 2026, announcing it would remove the extra row and standardize pitch back to 30 inches across the 737 fleet. Air Canada’s 737 MAX 8 economy pitch sits at 30-31 inches. After the rollback, the two airlines are comparable in standard economy.

Widebody economy. WestJet’s 787-9 Dreamliner offers 31-35 inches of pitch depending on seat location, with 276 economy seats. Air Canada’s 787 and 777 fleets offer 30-34 inches. Both are in the normal range for long-haul economy. WestJet’s 787 seats are 17.5 inches wide; Air Canada’s are 17.3 inches.

Premium economy. Both airlines offer premium economy on widebody routes at 38 inches of pitch. WestJet’s 787 has 28 premium economy seats; Air Canada offers premium economy on 787s and 777s with 37-38 inches and improved meal service. This is effectively a tie.

Business class. This is where Air Canada separates itself. Air Canada Signature Class on widebodies (787, 777) features lie-flat pods with direct aisle access, quality bedding, and catering that gets genuine praise from frequent flyers. WestJet’s 787 business class has 16 lie-flat seats at 46-inch pitch and 21-inch width, which is competitive but smaller in scale and less refined in soft product. Air Canada also offers business class on narrow-body transcontinental routes. WestJet’s narrow-body business equivalent is its Premium cabin, which offers extra legroom and meal service but not a lie-flat seat.

Wi-Fi and entertainment. Air Canada offers seatback screens on widebody aircraft. WestJet provides seatback screens on the 787 fleet. On narrow-body routes, neither airline consistently offers seatback IFE across the fleet. Neither offers free Wi-Fi; both charge for access.

Which airline is more reliable?

WestJet was more punctual in 2025. Both Canadian carriers trail US competitors like Delta, but WestJet’s improvement trajectory has been steeper.

WestJet posted a 78.6% on-time arrival rate for full-year 2025 per Cirium, with a 1.9% cancellation rate. The improvement from 2024 was substantial, up from roughly 71% when WestJet ranked at the bottom of the North American top 10. In October 2025, WestJet hit 84.66%, ranking first among all North American carriers that month.

Air Canada posted a 73.3% on-time rate for full-year 2025 per Cirium, also improving from 2024 but not as dramatically. Air Canada showed stronger monthly peaks, including 79.06% in May 2025 and 85.87% in November 2025, but less consistency across the calendar year. Air Canada operated 384,201 flights in 2025, nearly double WestJet’s 215,397, so the operational complexity is meaningfully higher.

For context, Delta led North America at 80.9% per Cirium for the fifth consecutive year. Both Canadian carriers trail the top US airlines, but the gap has narrowed.

Hub airports matter here. WestJet’s primary hub at Calgary (YYC) benefits from less congestion and fewer weather disruptions than Air Canada’s Toronto Pearson (YYZ), which is one of the most weather-impacted major airports in North America. If you connect through Calgary, your odds of an on-time departure are structurally better than connecting through Toronto.

WestJet / 78.6% vs 73.3% in 2025

Winner: peak monthly performance

Air Canada / 85.87% in November 2025

Winner: hub airport reliability

Winner: rebooking options after disruption

Air Canada / more daily flights, more destinations

Does WestJet or Air Canada fly to more places?

Air Canada serves 222 destinations in 63 countries. WestJet serves 139 destinations. Air Canada’s network advantage is the biggest single differentiator between the two airlines.

Air Canada operates from four major hubs: Toronto Pearson (YYZ), Montreal Trudeau (YUL), Vancouver (YVR), and Calgary (YYC). The fleet of 160 aircraft includes A220s, A320-family jets, 737 MAX 8s, 787 Dreamliners, and 777s. Star Alliance membership means codeshare access to United, Lufthansa, ANA, Singapore Airlines, and 20+ other carriers. For summer 2026, Air Canada added new routes to Berlin, Shanghai, Catania, Palma de Mallorca, and year-round Vancouver-Bangkok service.

WestJet is centered on Calgary (YYC) with secondary operations from Toronto, Vancouver, and Winnipeg. The fleet of 110 aircraft is predominantly Boeing 737s (737-700, 737-800, 737 MAX 8) plus seven 787-9 Dreamliners, with two more 787s on order as of February 2026. WestJet is not part of any global airline alliance, though it has interline agreements with several carriers. New 2026 routes include Reykjavik, Madrid, Copenhagen, and Medellin.

The practical difference for travelers: if your trip stays within Canada or goes to popular sun destinations (Mexico, Caribbean, Hawaii), WestJet covers most of what you need, often at lower fares. If you need connections to Europe beyond London and Paris, to Asia beyond Tokyo and Seoul, or to anywhere in Africa, South America, or the Middle East, Air Canada is the only realistic option from a Canadian gateway. Its Star Alliance partnerships extend the network far beyond what any single carrier could cover.

For US travelers flying into Canada, Air Canada’s Toronto hub offers the best connections to Eastern Canada and onward international flights. WestJet’s Calgary hub is the better entry point for the Canadian Rockies, Banff, and Western Canada.

Loyalty programs: WestJet Rewards vs Aeroplan

Aeroplan is the more powerful program. WestJet Rewards is simpler. They solve different problems, and the gap in international flexibility is significant.

This is where the “legacy vs value” distinction still holds. Aeroplan is one of the world’s top airline loyalty programs, consistently ranked among the best for premium cabin redemptions. WestJet Rewards is a straightforward earn-and-burn currency that works well within WestJet’s own ecosystem.

How they earn. WestJet Rewards earns WestJet dollars, where one WestJet dollar equals one Canadian dollar toward a future WestJet booking. The earn rate varies by fare class and WestJet Rewards tier (Silver, Gold, Platinum). Aeroplan moved to a spend-based model in 2026, earning points based on dollars spent rather than distance flown. Aeroplan also earns through 15+ transfer partners and over a dozen co-branded credit cards in Canada (TD, CIBC, Amex).

How they redeem. WestJet dollars apply only to the base fare on WestJet flights. Taxes, fees, and surcharges must be paid in cash. This is the biggest limitation of the program. Aeroplan points redeem across 40+ Star Alliance airlines, plus hotel and car rental partners. For premium cabin awards to Europe or Asia, Aeroplan’s pricing is consistently competitive.

Credit cards. WestJet has two co-branded cards through RBC, headlined by the WestJet RBC World Elite Mastercard, which includes a first checked bag free and an annual companion voucher. Aeroplan has more than a dozen co-branded cards across TD, CIBC, and Amex, with premium cards adding Maple Leaf Lounge access, priority boarding, and priority baggage.

Alliance access. Air Canada’s Star Alliance membership means Aeroplan points work across United, Lufthansa, Swiss, ANA, Singapore Airlines, Turkish, and more. WestJet is not in any alliance. WestJet Rewards points work only on WestJet.

For domestic-only flyers, WestJet Rewards’ simplicity is a real advantage. No award charts, no blackout confusion, no dynamic pricing games. One dollar earned is one dollar spent.

For anyone who flies internationally, Aeroplan is not just better, it is in a different category entirely.

Winner: simplicity

WestJet Rewards / dollar-for-dollar, no charts

Winner: credit card ecosystem

Aeroplan / 12+ co-branded cards vs 2

Who Should Pick WestJet

• You fly mostly within Canada or to sun destinations (Mexico, Caribbean, Hawaii) and want lower base fares
• You are based in Calgary or Western Canada and WestJet’s hub is your home airport
• On-time reliability matters and you want the Canadian carrier with the stronger 2025 track record (78.6%)
• You prefer a simple loyalty program where earned dollars translate directly to booking value
• You are flying to London, Paris, Dublin, or Edinburgh from Calgary on the 787 Dreamliner and want a direct flight without connecting through Toronto
• You travel with pets in-cabin frequently (WestJet charges roughly $37 CAD vs Air Canada’s $88 CAD)
• You value the WestJet RBC World Elite Mastercard companion voucher for annual trips with a partner

Who Should Pick Air Canada

• You need international connections beyond WestJet’s limited long-haul network, especially to Asia, Africa, South America, or smaller European cities
• You want Star Alliance access for earning and redeeming on United, Lufthansa, ANA, Singapore Airlines, and 20+ other carriers
• You fly in business class and want Air Canada Signature Class lie-flat pods with direct aisle access
• You are based in Toronto, Montreal, or Eastern Canada where Air Canada’s hub advantage is strongest
• You are an Aeroplan points optimizer using TD, CIBC, or Amex co-branded cards with transfer partnerships
• You need the flexibility of rebooking across a larger network when disruptions happen (384,000+ annual flights vs 215,000+)
• You are a frequent traveler pursuing elite status that gets recognized across 26 Star Alliance member airlines

The Bottom Line

WestJet and Air Canada have never been closer in product quality, and they have never been further apart in strategic identity. WestJet has grown up from a budget carrier into a credible full-service competitor with 787 Dreamliners, lie-flat business class, and long-haul routes to three continents. Air Canada has responded by tightening its own economy fares, stripping carry-ons from Economy Basic, and competing harder on price in domestic markets.

The result is that on a Calgary-to-Vancouver flight, the two airlines are nearly interchangeable. Same carry-on rules, same checked bag fees, same economy pitch, similar fares. The differentiation shows up at the extremes: WestJet is still cheaper on average for domestic and sun routes, while Air Canada is the only option for global reach, Star Alliance connectivity, and a genuinely premium international cabin.

Pick WestJet if your travel stays within Canada and the destinations it serves. Pick Air Canada if your travel extends beyond that or if Aeroplan’s international redemption value matters to your points strategy. If you fly both equally, the honest answer is to stay flexible. Neither airline has earned unconditional loyalty from Canadian travelers, and healthy competition between the two is the best thing that has happened to Canadian aviation.
