Airline Capacity Cuts Amid Rising Fuel Costs: WestJet, Transat and Others Reduce Flights in North America and Caribbean

Air Transat and WestJet are reducing their flight capacities in response to escalating aviation fuel costs linked to the war in Iran, marking a significant adjustment in Canadian airline operations during the peak summer travel season.

Transat A.T. Inc., the parent company of Air Transat, announced a six per cent reduction in overall capacity from May to October 2026, citing sustained high jet fuel prices as the primary driver. The airline specified that most of this reduction stems from the extended suspension of service to Cuba, which remains in place due to the ongoing U.S. Fuel embargo on the island nation.

WestJet simultaneously confirmed similar measures, scaling back its flight network in response to the same cost pressures. Both carriers made the announcements this week as fuel expenses continue to weigh heavily on the sector, with executives noting that demand remains strong despite the financial strain.

The recent volatility in aviation fuel prices reflects an exceptional environment affecting the entire sector. We are closely monitoring the situation, as cost pressures continue to be felt across the industry.

Industry experts warn that the current fuel crisis is unprecedented, driven by supply constraints stemming from the conflict in Iran. The volatility in jet fuel prices has forced multiple airlines to revise schedules and reduce frequencies on key international routes, particularly to Europe and the Caribbean.

Air Transat’s adjustments include reducing flight frequency on select transatlantic and Caribbean routes, with the prolonged Cuba suspension accounting for the majority of the capacity cuts. The airline emphasized that these changes are temporary and tied directly to fuel cost volatility, not shifts in passenger demand.

WestJet’s capacity reductions follow a similar pattern, though specific route details were not disclosed in the latest announcements. Analysts caution that further cuts may be necessary if fuel prices remain elevated or increase through the summer months.

The coordinated moves by two of Canada’s largest leisure and regional airlines underscore the widespread impact of fuel cost inflation on aviation operations. As the summer travel period begins, both carriers are prioritizing cost management while maintaining core service levels on profitable routes.
