Air Canada vs WestJet (2026): Which Should You Actually Book?

One is Canada's global premium hub-carrier with a Star Alliance passport and a Skytrax-winning suite; the other is the scrappy Calgary challenger that quietly gave every passenger free Starlink WiFi before most of the world had heard of it.

This is the most Canadian rivalry in aviation, and it is not a fair fight in the way you’d expect. Air Canada (AC) is a 4-star Star Alliance flag carrier flying 787-9s out of Toronto and Vancouver to 30-plus longhaul destinations, with an Aeroplan programme that books award tickets across half the planet. WestJet (WS) started as a Calgary low-cost upstart and has spent the 2020s morphing into a 737-MAX-and-787 transatlantic challenger with 168 routes and a leisure-heavy network into Iceland, Dublin, and the UK regions. On paper AC is the premium one. But WestJet pulled off the single most consumer-friendly move in North American flying — free Starlink WiFi for everyone — and its cheapest fare carries a CAD 0 change fee where Air Canada charges around €100. For the deal-hunter booking the rock-bottom economy seat, this comparison genuinely goes either way.

Network & hubs: the global flag carrier vs the transatlantic challenger

Air Canada is a hub-and-spoke flag carrier built around Toronto Pearson (YYZ), Montréal (YUL), and Vancouver (YVR), funnelling traffic onto 787-9 widebodies bound for Europe, Asia, South America, and Australasia. Its strength is depth on premium longhaul corridors out of YYZ and YVR. WestJet is the opposite shape: a Calgary (YYC) operation with a far wider breadth — 57 destinations across 168 routes versus Air Canada’s 30 destinations on 56 routes in our data — but skewed leisure and short-haul. The WestJet map tells the story: Toronto, Calgary, Reykjavík, Dublin, Halifax, Cardiff, Edinburgh, Glasgow. That’s a carrier chasing UK-and-Iceland transatlantic value and Western-Canada domestic loyalty, not a global network. If you’re connecting onward to Tokyo or Santiago, Air Canada is the only one of the two that can actually carry you there. If you’re flying Calgary–Glasgow or a sun route, WestJet probably owns the cheaper nonstop.

WestJet gave every passenger free Starlink WiFi before Air Canada finished arguing about whether broadband should be a member perk.

The cheapest fare: both strip the bag — but the change fee splits them

This is the section aifly readers care about most, and it’s the clearest verdict in the whole comparison. Both airlines sell a hand-only cheapest fare: Air Canada’s Basic Economy (on transborder and selected routes) excludes the checked bag, and WestJet’s Basic fare is hand-only too. Neither gives you a free seat assignment at the bottom. So far, a tie — you’re buying a personal item and paying for everything else on either. The split is the change fee: WestJet’s Basic carries a CAD 0 change fee, while Air Canada’s cheapest fares run around €100 to change. For a flexible traveller hunting a cheap economy seat, that asymmetry is real money. The trap on both: Basic/Basic Economy is the one fare where you genuinely get nothing but a seat and a personal item — read the fine print before you assume a roller bag is coming.

The free stopover: Air Canada's Aeroplan trump card

Here Air Canada wins outright, and it’s not close. The Aeroplan programme lets you add a stopover to an award ticket for just 5,000 points — one per one-way, two per round-trip — lasting up to 45 days, on travel outside Canada and the US. In plain terms: you can fly to Europe and spend a week (or three) in a second city on the same award for a token points top-up. It is one of the best stopover sweet spots in the loyalty world, and it’s a genuine reason to bank on Aeroplan. WestJet has no equivalent self-service stopover product; its ‘visit two places’ play is whatever your routing happens to allow, not a published programme. If free multi-city travel is your thing, Aeroplan is the entire argument. Note this is an award perk — it doesn’t apply to a cash Basic fare — but it’s the reason frequent flyers pick AC’s ecosystem.

Connectivity: WestJet's Starlink coup vs Air Canada's member broadband

WestJet did something most flag carriers are still promising: it rolled out free Starlink WiFi to every Rewards member, fleet-wide, becoming the first commercial 737 operator to fly Starlink. As of the rollout, around 151 of 159 aircraft were equipped, with widebody 787s slated to finish by end of 2026. It’s fast, low-latency, genuinely free (you just join the free Rewards programme), and it embarrasses most of the industry. Air Canada offers broadband WiFi too, but tiered toward members rather than a blanket free-for-all, and the experience is the conventional ‘connect, sometimes pay’ model. For anyone who wants to actually work or stream in the air, this is a clean WestJet win — arguably the single best reason a value traveller picks the challenger over the flag carrier. The catch: confirm your specific WestJet aircraft is Starlink-equipped, as the last widebodies are still being fitted.

Same 75% on-time number, same hand-only cheapest fare — so the tiebreakers are the stopover, the WiFi, and the change fee.

Cabin & comfort: seatback screens vs stream-to-your-phone

On hard product, Air Canada is the more polished longhaul ride. Its 787-9s carry proper seatback IFE screens, a Signature Class business cabin up front, and a snack-included economy; legroom sits at about 31 inches of pitch. WestJet runs a younger fleet on average (around 10 years vs Air Canada’s 12), led by the 737-MAX, with a lie-flat business seat on its 787s — but economy IFE is mostly streaming-to-your-device rather than seatback screens, and pitch is a touch tighter at roughly 30 inches. Skytrax rates Air Canada 4 stars to WestJet’s 3, and that gap shows up exactly where you’d expect: the widebody longhaul experience. For a transatlantic hop WestJet’s MAX cabin plus free Starlink is perfectly pleasant; for a 12-hour flight to Asia, Air Canada’s seatback screen and Signature product is the one you want. Both serve a snack in economy — nobody’s getting a feast at the back.

Points, status & alliance: a Star Alliance passport vs a partner patchwork

Air Canada’s Aeroplan sits inside Star Alliance, which means earn-and-burn across Lufthansa, United, ANA, and dozens more, plus Star Alliance Gold lounge access when you have status — a true global passport. WestJet Rewards is not in a global alliance; instead it has stitched together a partner patchwork: a deepened Virgin Atlantic Flying Club tie-up (reciprocal earning across networks and VS–WS codeshares), plus partner flights on SkyTeam (Air France, KLM, Delta) and Oneworld (American, Qantas), and a new Petro-Canada fuel-loyalty link. WestJet points are simple — roughly CAD 1 of fare value per point — which is transparent but caps your ceiling. The verdict: if you collect miles seriously and want lounge access and aspirational redemptions, Aeroplan/Star Alliance is the deeper, more valuable ecosystem. WestJet Rewards is fine for a Western-Canada regular who values clarity over a sprawling award chart.

Reliability & safety: identical punctuality, so it's a wash

Here the two airlines are genuinely indistinguishable. Both posted a 75% on-time arrival rate in Cirium’s 2025 annual figures — below-average versus global peers, and a real demerit for both. Neither carrier can sell you on punctuality; if you have a tight onward connection, build in buffer regardless of which tail you fly. On safety, both are modern North American operators flying current-generation Boeing and Airbus metal (Air Canada’s A220/737-MAX/787 mix, WestJet’s 737-MAX/787) with the regulatory oversight that implies — no meaningful daylight between them. So reliability and safety effectively cancel out, which is precisely why the booking decision falls back on the things that do differ: the stopover, the WiFi, the change fee, and whether you need a real longhaul widebody network. Don’t let either airline’s marketing convince you one is materially more dependable than the other — the numbers say they’re twins.

So — which one?
