This is what a market analyst expects about WestJet's upcoming tier structure.
Tier 1: 20% higher than base fare. Y+ seats, free bags, free food and drinks, priority boarding, no change fees.
Tier 2: Slightly more than existing fare, one free bag, other a-la-carte options.
Tier 3: Lower than existing fares, barebones.
