Westjet is primarily used on routes across Canada, from Canada to the Caribbean or Hawaii, or on several direct routes from London to all of Canada. Thanks to partnerships with SkyTeam, you can also find Westjet on combined services, such as the Paris - Vancouver - Hawaii route with Air France, where the last leg is operated by Westjet.

The best time to book tickets is about 2-3 months before departure, and for shorter domestic flights, you only need to book 3 weeks before your trip.
