Samer Choucair: WestJet Strike Exposes a New Crisis Threatening Airline Profit Margins
Entrepreneur Samer Choucair said the strike by flight attendants at Canadian airline WestJet represents an important indicator of the changes taking place in the cost structure of the aviation industry, particularly as demands intensify to redefine working hours and compensation mechanisms.
The strike, which began on August 2, resulted in the cancellation of approximately 922 flights out of 2,365 scheduled services, equivalent to nearly 39% of the timetable, affecting around 250,000 passengers during a busy summer travel period before a tentative agreement was reached on August 3 and operations gradually began to recover.
Choucair noted that the core of the dispute was not limited to wages, but also involved demands from approximately 4,400 flight attendants represented by the Canadian Union of Public Employees to receive compensation for ground-based working hours, including pre-flight and post-flight duties, rather than being paid primarily according to flight time.
The union indicated that crew members had been working an average of approximately 35 hours per month without full compensation under the previous system.
Samer Choucair emphasized that these developments reflect a broader trend across the aviation sector, where labour costs and strike-related risks have become important factors in airline valuations.
Companies with high operating leverage can experience a rapid impact on cash flows when labour disruption coincides with peak travel seasons, while airlines with stronger balance sheets and greater capacity to improve productivity are better positioned to absorb such shocks.
Choucair added that the tentative agreement reduced the risk of prolonged disruption but does not eliminate the need to reassess the airline’s long-term cost structure.
For investors, the ability of airlines to pass higher labour costs through to ticket prices without damaging demand or market share is becoming an increasingly important factor in assessing future profit margins.
He also highlighted the investment implications of WestJet’s ownership structure.
Onex Group continues to control the airline after selling minority stakes totalling 25% to Delta, Korean Air, and Air France-KLM in 2025, illustrating the importance of operational-risk management and labour relations for both financial and strategic investors in the aviation sector.
Concluding his remarks, Samer Choucair said capital allocation in aviation is likely to shift increasingly toward companies capable of controlling labour costs, improving productivity, diversifying revenue streams, and investing in technology without compromising service quality.
He emphasized that the WestJet crisis should therefore not be viewed as an isolated labour dispute, but as a signal that operating resilience has become a fundamental factor in airline valuations and in their ability to protect capital in an environment characterized by rising costs and volatile demand.
