In a country traditionally dominated by two national airlines, a new set of aviation rivalries has emerged.

Porter is increasingly moving in on Air Canada’s home turf of Central Canada as well as cross-country routes, while WestJet seeks to counter the threat of Flair Airlines in a shift from the decades-old industry dynamic of sparring between the two biggest carriers.

Here’s how the airlines’ share of domestic flight capacity has changed over the years, according to data from OAG and National Bank Financial.

2019:

Air Canada: 48 per cent

WestJet: 34 per cent

Porter: 4 per cent

Flair: 1.5 per cent

2024:

Air Canada: 41 per cent

WestJet: 30 per cent

Porter: 10 per cent

Flair: 8 per cent
