How to book award flights on major Canadian airlines using other points programs

What does "booking an award flight" actually mean?

When you collect points or miles with an airline or a credit card, you can eventually trade those points for a flight instead of paying cash. This is called an award booking or award flight.

This guide is specifically about booking award flights on Canada's three major airlines — Air Canada, WestJet, and Porter — using loyalty programs other than their own. That strategy is called booking through a partner program, and it can sometimes get you the exact same seat for significantly fewer points.

Most people assume the simplest approach: if you want to fly Air Canada, use your Air Canada points (called Aeroplan). If you want to fly WestJet, use your WestJet points. That instinct makes sense — it's how most people get started, and it works perfectly well most of the time.

But here's something that surprises a lot of beginners: airlines share their seats with other loyalty programs. That means the exact same flight — same plane, same seat, same departure time — can often be booked using points from a completely different program. And sometimes, that other program charges fewer points for the very same flight.

Below, we walk through which partner programs are worth checking for each Canadian airline, and how to decide which one gives you the best deal.

A quick note on alliances and partnerships

Before we dive in, it helps to understand why this is even possible.

Airlines don't operate in isolation. They form partnerships and groups (called alliances) so their customers can earn and spend points across each other's networks. Air Canada, for example, belongs to a global group called Star Alliance, which includes airlines like United. That means United's loyalty program can sometimes book seats on Air Canada flights — and vice versa.

These partnerships are why one flight can show up in multiple programs. It's not a loophole. It's how the system is designed.

The practical takeaway: before you book, it's worth checking more than one program. You might find the same flight for significantly fewer points elsewhere.

Air Canada: Aeroplan is a great starting point, but not always the cheapest

Aeroplan is Air Canada's loyalty program, and it's the most natural place to search when you want to fly Air Canada. It has a wide range of flights, good search tools, and it integrates well with many Canadian credit cards.

The catch is that Aeroplan uses dynamic pricing on many Air Canada flights. Dynamic pricing means the number of points required isn't fixed — it goes up and down based on demand, just like cash ticket prices do. On a busy travel weekend or a last-minute booking, the points price can jump significantly.

Here's where it gets interesting. Because Air Canada is part of Star Alliance, the same flight can also be booked through:

• United MileagePlus (United Airlines' loyalty program)
• Etihad Guest (the loyalty program for Etihad Airways, based in Abu Dhabi)
• Other Star Alliance member programs

These programs often use fixed or zone-based pricing — meaning the points cost stays the same regardless of when you're traveling or how popular the flight is. On short domestic routes booked close to departure (when Aeroplan prices tend to spike), this difference can be dramatic.

Example: A flight from Ottawa (YOW) to Toronto (YYZ) might cost roughly 21,000+ Aeroplan points, but the same flight could be available for around 5,867 Etihad Guest Miles. That's a difference of more than 15,000 points for an identical flight.

The lesson: Aeroplan is often the right choice — especially for complex itineraries or when you have a lot of Aeroplan points saved up. But when a domestic Air Canada route looks expensive in Aeroplan, it's worth checking Etihad Guest or United MileagePlus before you book.

WestJet: flexibility can matter as much as price

WestJet Rewards is WestJet's own loyalty program, and it's the obvious first place to look. But WestJet has built partnerships with several major international airlines, which means some WestJet flights can also be booked through:

• Delta SkyMiles (Delta Air Lines' loyalty program)
• Air France-KLM Flying Blue
• Virgin Atlantic Points

Why does this matter? Two reasons: price and flexibility.

On the price side, some WestJet flights are available for fewer points through Flying Blue or Virgin Atlantic than through WestJet Rewards directly.

On the flexibility side, some WestJet award bookings made through Delta's program come with better cancellation terms — meaning if your plans change, you may be able to cancel and get your points back more easily than you could with WestJet Rewards.

This is an important concept for beginners: the cheapest award isn't always the best award. If there's any chance your travel plans might change, a slightly more expensive but fully cancellable award can be worth it. Being stuck with a non-refundable booking — or paying a big cancellation fee — can wipe out any savings you got from a lower points price.

The lesson: When booking WestJet, don't just ask "how many WestJet points does this cost?" Also ask: What does it cost through Delta, Flying Blue, or Virgin? And what happens if I need to cancel?

Porter: one partnership you should always check

VIPorter is Porter Airlines' loyalty program. It's a straightforward program, and it's a reasonable place to start.

What many people don't know is that Porter also has a loyalty partnership with Alaska Airlines, through a program called Atmos Rewards. This means some Porter flights can be booked using Atmos Miles — and on certain routes, Atmos can require fewer miles than VIPorter for the same seat.

Atmos also has a handy flexibility feature: you can cancel an award booking before your flight departs for no cancellation or redeposit fee. The only cost you'd lose is a small USD $12.50 booking fee per direction, which is non-refundable. For many travelers, that's a worthwhile trade for peace of mind.

The lesson: Whenever you're pricing a Porter flight through VIPorter, take two minutes to also check Alaska Atmos Rewards. It won't always be cheaper, but it sometimes is — and the cancellation policy alone can make it worth using.

How to compare the same flight across programs

When you find a flight available in more than one loyalty program, here's what to compare before deciding where to book:

1. Total points required. This is the obvious one — but make sure you're looking at the complete cost, not just a headline number. 2. Taxes, fees, and surcharges. Some programs pass along airport taxes and airline fees; others don't. A booking that costs fewer points but adds $100 in fees might not actually be cheaper overall. 3. Cancellation and redeposit rules. What happens if your plans change? Can you cancel and get your points back? Is there a fee? 4. How easy it is to get those points. If you'd have to open a new credit card, transfer from a bank program, or earn miles from scratch, factor in that effort. 5. Ease of booking. Some partner bookings are seamless online; others require calling an airline's customer service line.

Going through that list only takes a few minutes, and it can save you thousands of points or a frustrating experience if plans change.

The bottom line

Here's the habit worth building:

• Start with the airline's own program (Aeroplan for Air Canada, WestJet Rewards for WestJet, VIPorter for Porter).
• Then check the partner programs that can book the same flight.
• Compare points cost, fees, and cancellation terms before you commit.

For Air Canada, the partners worth checking are United MileagePlus and Etihad Guest. For WestJet, look at Delta SkyMiles, Air France-KLM Flying Blue, and Virgin Atlantic Points — especially if flexibility matters. For Porter, add Alaska Atmos Rewards to your comparison.

You won't always find a better deal through a partner program. But when you do, the savings can be significant — and the only extra step is a quick search before you book.
