Ask ten Canadians which airline they prefer and you’ll get ten stories about a delayed flight, a helpful gate agent, or a sandwich that cost eleven dollars. Stories are fun, but they don’t help you book. Numbers do. So this guide sticks to what changed in 2026 and what it costs you: the spring baggage fee hikes, the on-time performance data, the loyalty program math, and where the smaller carriers now fit.
If you want the broader service-and-vibe rundown, we already wrote an honest Air Canada vs WestJet comparison. Think of this post as its sharper, spreadsheet-carrying sibling.
The 2026 news that changed the math
Two things happened this spring that quietly rewrote the value equation for Canadian flyers.
First, both airlines raised checked bag fees within ten days of each other. Air Canada moved on April 13, 2026, and WestJet followed on April 23, each adding roughly $10 per bag on domestic and transborder routes, with both carriers pointing at fuel costs (CBC News). As of August 2026, a first checked bag on an Air Canada Economy Basic domestic fare runs about $45 to $54 one way. On WestJet’s cheapest UltraBasic fares it can hit $60 to $93 depending on when and where you pay (Daily Hive). A bag can now cost more than the fare on a good sale day. That is not an exaggeration, it is a Tuesday on our deals page.
Second, WestJet had a genuinely strong operational spring. In Cirium’s May 2026 report, WestJet ranked first in North America for on-time performance, with nearly 86 percent of its flights arriving on schedule, and it was the only Canadian carrier to crack the global top ten. Air Canada came seventh in North America at roughly 79 percent (Daily Hive).
Neither fact settles the debate on its own. Together, they reshape it.
Pricing reality: the sticker price is a rumour
On competitive routes, base fares between the two are usually within a few dollars of each other. Both airlines watch each other’s pricing the way hockey parents watch refs. Where the real gap opens is everything after the base fare.
Air Canada’s cheapest domestic tier (Economy Basic) and WestJet’s UltraBasic are both stripped to the studs: no seat selection, no changes, and on WestJet’s UltraBasic you don’t even get a standard carry-on in the overhead bin, just a personal item. WestJet’s version is the more aggressive of the two, which is why its cheapest fares sometimes undercut Air Canada by $20 or $30. You are meant to give that money back at the baggage counter.
The practical rule for 2026: compare total trip cost, not fare. A $189 fare with a $71 bag loses to a $229 fare with a $45 bag, and both lose to packing a carry-on. Our carry-on only guide exists for exactly this reason, and when you run a search on FareSeeker, assume the cheapest fare class shown is bag-free until proven otherwise.
Baggage and fees, side by side
Here is where the two stand as of August 2026 for domestic economy travel. Fees vary by route, fare class, and whether you prepay online, so treat these as the realistic range rather than a promise.
| What you’re paying for | Air Canada | WestJet |
|---|---|---|
| First checked bag (basic fares, domestic) | ~$45 to $54 | ~$60 to $93 (UltraBasic), ~$45 to $81 (Econo) |
| Second checked bag | ~$60 to $81 | ~$60 to $111 |
| Carry-on on cheapest fare | Included | Personal item only on UltraBasic |
| Seat selection (standard) | Extra on Basic/Standard | Extra on UltraBasic/Econo |
| May 2026 on-time arrivals (Cirium) | ~79% (7th in North America) | ~86% (1st in North America) |
| Loyalty program | Aeroplan | WestJet Rewards (points) |

Reliability: WestJet’s year, with an asterisk
The full-year 2025 numbers were close: Flair led Canadian carriers at 74.2 percent on-time arrivals, WestJet posted 73.6 percent, and Air Canada 73.3 percent, with both big carriers improving on 2024 (Open Jaw). Through 2026 the gap has widened month by month. WestJet edged Air Canada in Cirium’s January and March tables, then lapped the field in May.
Now the asterisk. Air Canada operates a far bigger and more complicated network. In May it flew over 200,000 flights across six continents while WestJet flew about 18,000, mostly domestic and sun routes. Long-haul international networks collect delays the way white shoes collect scuffs. If your trip is Calgary to Kelowna, WestJet’s punctuality edge is real and relevant. If your trip is Toronto to Tokyo, Air Canada is often the only nonstop game in town, and its schedule padding on international routes means the raw percentage matters less than you’d think.
Winter is the other caveat. Both airlines’ on-time numbers sag hard in December and January, and no loyalty status shovels a runway. Know your rights under Canada’s air passenger protection rules before you fly, not after.
Aeroplan vs WestJet Rewards: different games entirely
This is the least symmetric part of the comparison, because the two programs aren’t trying to do the same job.
Aeroplan is a points ecosystem with global reach. Through Star Alliance and partner airlines you can earn on an Air Canada hop to Montreal and burn on a flight to Bangkok. Redemption pricing follows distance-based charts with dynamic pricing on Air Canada’s own flights, and sweet spots still exist if you hunt. The catch is complexity. Getting outsized value from Aeroplan is a hobby. Our Aeroplan 101 guide covers the basics without the spreadsheet obsession.
WestJet Rewards went through its biggest change ever in April 2025, converting WestJet dollars into WestJet points at 1:100 and letting members cover the entire cost of a booking with points, taxes and fees included (Milesopedia). Value per point is essentially fixed, which means no jackpot redemptions but also no feeling robbed. In February 2026 WestJet deepened its partnership with Virgin Atlantic, letting members earn and redeem across each other’s networks including codeshares (WestJet newsroom), a sign the program wants international relevance without Aeroplan’s complexity.
The honest summary: if you fly internationally more than twice a year or enjoy points optimization, Aeroplan offers a higher ceiling. If you fly domestic and sun routes and want your points to just work like a gift card, WestJet Rewards is simpler and harder to misuse.
Where Flair and Porter fit in 2026
The duopoly framing misses half the story now.
Flair has quietly stopped calling itself an ultra-low-cost carrier at all, shifting toward a more traditional model while running a fleet of about 20 Boeing 737s (ch-aviation). It rebuilt eastern routes this spring, reconnecting Toronto with St. John’s and Moncton and resuming Vancouver to Montreal (Travel Market Report). On routes where Flair shows up, fares from all carriers tend to drop. It also topped Canada’s 2025 on-time rankings, which surprises people who haven’t flown it lately. Our Flair review covers the trade-offs in detail.
Porter is the bigger strategic story. It took delivery of its 50th Embraer E195-E2 in December 2025, with firm orders for 75 and rights for up to 100 (Embraer), and it will fly more than 10 million seats in 2026. Porter sells free WiFi, free snacks and drinks, and no middle seats at prices that compete with the big two’s economy fares. On corridors like Toronto to Vancouver, that third and fourth competitor is the main reason fares stay honest. Check current pricing on the Toronto to Vancouver route page and you’ll usually find all four carriers within striking distance of each other.
So who wins in 2026?
Nobody wins everything, which is the healthiest answer a market can give.
- Book WestJet if you fly within Western Canada or to sun destinations, value punctuality, and want a loyalty program that behaves predictably. Avoid UltraBasic unless you can genuinely travel with a personal item only.
- Book Air Canada if you fly internationally, need the network depth for connections, or are invested in Aeroplan. Accept that on-time performance has trailed WestJet all year.
- Book Porter when it flies your route and comfort matters. It is the best per-dollar cabin experience in the country right now.
- Book Flair when the total price, bags included, actually beats the others. Sometimes it does, sometimes the fees close the gap.
And whoever you lean toward, let the fare decide the tiebreaker. Set an alert, watch the latest deals, and be the traveller who books the $250 round trip while everyone else argues about sandwiches.
FAQ
Is WestJet actually cheaper than Air Canada in 2026? On base fares, usually only by a little, and WestJet’s UltraBasic fares carry the steepest bag fees in the country at up to $93 for a first checked bag. Compare the total cost with your bags added. On many routes Air Canada, Porter, or Flair ends up cheaper once fees are in.
Which airline is more reliable right now? By the numbers, WestJet. It ranked first in North America for on-time arrivals in Cirium’s May 2026 report at about 86 percent, while Air Canada sat near 79 percent. Air Canada’s larger international network partly explains the gap, and both carriers struggle equally in Canadian winter.
Should I switch from Aeroplan to WestJet Rewards? Match the program to your flying, not the other way around. Aeroplan rewards international travel and effort. WestJet Rewards, after its 2025 points conversion, works like a simple rebate you can spend on any booking, taxes included. Frequent international flyers should keep Aeroplan. Domestic and sun-route flyers will find WestJet’s program easier to actually use.
