These combined factors have reduced operational flexibility, increased aircraft turnaround times, and contributed to cascading delays and cancellations across multiple Canadian airports as airlines work to recover schedules.

What Can Affected Passengers Do?

• Keep essential medications, chargers, travel documents, and other necessities in your carry-on baggage.
• Speak with your airline if your itinerary requires rebooking or alternate travel arrangements.
