Canada's airlines are fighting for customers through matching seat sales offering 50 per cent off to selected cities in Eastern Canada and the northern United States.

WestJet made its pitch for customers Friday by becoming the latest airline to offer the big discount to destinations like Halifax, Montreal and Ottawa.

It follows Air Canada and Porter Airlines who started offering the discounts earlier this week.

Porter is offering half off to anywhere it flies, while Air Canada's discount applies only to similar destinations as Porter.

The airlines were already fiercely competing for business travellers in the so-called "eastern triangle" of Toronto, Ottawa and Montreal.

The triangle is worth about $600 million in revenues annually.
