Which is the best airline for flying within Canada?
The best airline for flying within Canada depends on what you value. Air Canada has the widest network and most departures, WestJet balances price and service, Porter offers the most comfortable economy cabin, and Flair has the lowest base fares for travellers who pack light.
Air Canada
Air Canada operates the largest domestic network, reaching the most cities with the most daily frequencies. It is the strongest choice for connections, regional destinations and travellers who want a full-service experience with an Aeroplan loyalty programme. Fares sit at the higher end, but flexibility and reach are unmatched.
WestJet
WestJet is the main competitor to Air Canada and often the value sweet spot — reasonable fares with a friendly full-service experience on most routes. Its network is strongest in Western Canada, with a solid presence on transcontinental and leisure routes.
Porter Airlines
Porter is known for a more comfortable economy product — free in-flight snacks and a no-middle-seat layout on its newer jets. It has expanded rapidly across eastern and transcontinental routes and is a strong pick when comfort matters more than rock-bottom price.
Flair Airlines
Flair is Canada’s ultra-low-cost carrier, offering the lowest headline fares. The trade-off is unbundling: carry-on bags, checked luggage and seat selection all cost extra. For light packers on a flexible budget it can be the cheapest option — just compare the full price before booking.

| Airline | Best for | Fare level |

How should you choose?
Match the airline to the trip. For a quick mid-week hop where price rules, check Flair and WestJet first. For comfort on a longer flight, Porter is worth a small premium. For connections, regional airports or loyalty benefits, Air Canada leads. Always compare the total price including bags and seat selection.
