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

Two Canadian carriers chasing the same cheap-seat traveller across the Atlantic — one is scaling up fast with free Starlink, the other is a Skytrax 4-star leisure specialist that quietly strips your fare to the bone.

This is a fight between two theories of low-cost long-haul out of Canada. WestJet (WS) is the growth story: a Calgary-hubbed classic carrier with 61 destinations, a 737 MAX and 787 Dreamliner backbone, free Starlink wifi rolling out fleet-wide, and eight brand-new European nonstops for 2026. Air Transat (TS) is the incumbent leisure specialist — Montréal- and Toronto-based, 45 destinations, a modern Airbus A321LR fleet, and a Skytrax 4-star rating that WestJet’s 3 stars can’t match. Both sell a rock-bottom fare that hides real trade-offs, and both skip the perks — no global alliance, no free stopover, no lie-flat seat on the routes most of you will actually book. For aifly readers hunting the cheapest economy seat across the pond, the decision comes down to what each carrier’s bargain fare quietly leaves out.

Network & hubs: the coast-to-coast operator vs the Atlantic specialist

Two Canadian carriers, two opposite maps. WestJet runs a genuine coast-to-coast operation out of Calgary (YYC) — 61 destinations, 186 routes, a 737 MAX and 787 backbone — and in 2026 it’s going aggressive on Europe with eight new nonstops, adding cities like Glasgow and Cardiff alongside its established Dublin, Edinburgh, London Heathrow, Paris, Barcelona and Rome flying. Air Transat is the mirror image: a leisure specialist built at Montréal (YUL) and Toronto (YYZ), 45 destinations and 114 routes, tuned for the summer Atlantic and winter sun runs. Its European map — Nice, Athens, Valencia, Lisbon — is holiday-first and often deeper than WestJet’s on those leisure city-pairs. On aifly’s own feed WestJet appears roughly three times as often as a deal (3,008 vs 917 price observations), part size effect, part sheer aggression. Want breadth and connections? WestJet. Want a Montréal-or-Toronto-to-Europe holiday? Transat.

WestJet's real lie-flat business exists — just probably not on your flight to Europe.

The cheapest fare: Basic vs Eco Budget, two ways to strip a ticket bare

This is the section that matters most to aifly readers, and it’s the clearest split. WestJet’s entry fare is Basic: hand-baggage only, no checked bag, no free seat selection — but crucially a €0 change fee. Air Transat’s entry fare is Eco Budget, and it’s the most aggressively unbundled fare in this comparison: it excludes both a checked bag and the meal, keeps only a 10 kg cabin allowance, and stings you with a €100 change fee. That’s the honest hybrid-carrier signal — Transat’s headline number often looks cheapest on the grid precisely because it’s giving you the least. Add a 23 kg bag to a transatlantic Eco Budget (you’ll need Eco Standard, which bundles the bag and meal) and the ‘deal’ frequently evaporates. WestJet also tends to show up cheaper more often: its deal-floor and median both sit below Transat’s across aifly’s observations. Always compare the fare with a bag added, not the teaser.

Cabin & comfort: the lie-flat that probably isn't on your flight

Here’s a trap worth naming. WestJet does operate a genuine, excellent business class — 1-2-1 lie-flat suites on its Boeing 787-9 Dreamliner, 16 beds, on-demand dining, privacy screens. The catch: those Dreamliners stay based in Calgary, and WestJet’s eight new 2026 European routes fly on the narrowbody 737 MAX 8, where ‘business’ is a recliner, not a bed. So the shiny product exists — just probably not on your city’s nonstop. Air Transat counters with Club Class, a wide recliner premium cabin on its A321LR — comfortable, convivial, but explicitly not lie-flat business either. Down the back, economy is near-identical on paper: both offer 30 inches of pitch, with Transat marginally tighter at 17 inches wide versus WestJet’s 17.3. Transat’s saving grace is its Skytrax 4-star rating (WestJet holds 3) and a genuinely modern, quiet A321LR with USB-C and USB-A power at most seats.

Food: a hot meal with wine vs a bag of pretzels

On catering, Air Transat is the more serious airline — with a caveat. Its transatlantic service (Eco Standard and up) includes a complimentary hot meal with a choice of two mains, salad, bread, a sweet, and a beverage that includes wine, plus a later snack. That’s a real, sit-down leisure-flight experience and a big reason for the 4-star badge. WestJet’s Basic fare, by contrast, gets you a snack — this is a buy-up-or-go-hungry proposition on the narrowbody Europe routes. But the caveat cuts hard: Transat’s cheapest Eco Budget fare strips the meal entirely, dropping you to buy-on-board, so the food advantage only exists if you’ve already paid past the bargain tier. Net read: if catering matters and you’ll book Eco Standard, Transat wins comfortably; if you’re chasing the absolute cheapest seat on either airline, you’re eating what you brought or what you bought at the airport.

Eco Budget is the only fare here that strips the bag AND the meal in a single move.

Connectivity: free Starlink vs no signal at all

This is WestJet’s single most decisive win, and it’s a genuine one. Through its TELUS partnership, WestJet is fitting free Starlink wifi across the fleet — fast, satellite-based, and complimentary to WestJet Rewards members. The narrowbody rollout wrapped in 2025 and the widebodies are slated to finish by the end of 2026, so on the 737 MAX routes to Europe you can realistically expect to stream. Air Transat is nowhere close: its A321LRs aren’t wired for broadband wifi, and there’s no sign that changes soon — you’re offline over the Atlantic. Be honest about the rollout timing (WestJet’s own language is ‘planned’ for full widebody coverage by late 2026, so check your specific aircraft), but even accounting for that, this is a rout. If staying connected on a seven-hour crossing is worth anything to you, WestJet is the only airline here that offers it, and offers it free.

Reliability & safety: a dead heat on time, clean records in the air

Neither airline will win a punctuality award. Both posted a 75% on-time rate in Cirium’s 2025 annual data — respectable-sounding but below the North American average, so build in buffer on tight connections. Fleet-wise, both fly young metal: WestJet averages about 10 years (737 MAX and 787), Air Transat about 9 (the A321LR is one of the newest single-aisle types flying the Atlantic). Safety records are clean and modern; the A320 family Transat flies is statistically among the safest single-aisle fleets ever built, and the 737 MAX has long since returned to routine service. The nuance that separates them isn’t safety but exposure: Transat’s all-Airbus narrowbody Atlantic model means a very consistent, quiet ride, while WestJet’s mix gives you a shot at the far more spacious 787 experience — but only ex-Calgary. On the metrics that a nervous flyer cares about, call it even.

Points & alliance: two independents, and one brand-new loyalty card

Don’t fly either of these for status. Neither WestJet nor Air Transat belongs to a global alliance — no Star Alliance, oneworld or SkyTeam earning, no reciprocal lounge web, no free-stopover programme on either side. WestJet at least has an established, straightforward frequent-flyer scheme in WestJet Rewards (and, notably, that free membership is what unlocks the complimentary Starlink wifi — so sign up regardless). Air Transat is mid-reset: it suspended its old BonBon programme in 2025 and is launching a new Desjardins/Visa co-branded loyalty programme in the second half of 2026, with earning rates, bag and lounge perks still unannounced as of now. For lounges, WestJet has a real flagship — the Elevation Lounge in Calgary, widely rated among the best in Canada — while Transat relies on contract lounge access for Club Class. If you collect, WestJet is the more coherent ecosystem today; Transat is a wait-and-see.

So — which one?
