As you may know, Air Canada is in contract discussions with our pilots’ union, who are in a legal strike position as of September 18.

While Air Canada remains highly committed to reaching an agreement with our pilots, we cannot be certain of the outcome of our negotiations. Our first consideration is always the needs of our customers and providing them with peace of mind.

Your flight is scheduled to operate normally at this time. However, in the event of a work stoppage, some flight cancellations could begin as early as September 15. In order to give you the best options available, on August 27, we introduced a policy allowing you to change your flight for free. If you are flexible and this meets your needs, we strongly encourage you to consider taking advantage of this policy.

Changing your plans

• To change your travel plans, you can rebook your flight at no cost, subject to availability in the cabin you originally purchased, up to two hours before your departure time.
  
• You may choose an alternate travel date between:
  • September 9, 2024, and September 14, 2024
  • September 24, 2024, and November 30, 2024
    
• If you booked directly with Air Canada, please call us at 1‑888‑247‑2262 (for international and other numbers, visit aircanada.com/othernumbers).
  
• If you booked through Air Canada for Business, a travel agency, or online travel website, please contact your booking source directly.
  
• If you have booked with Air Canada Vacations, you can reach them directly at 1‑866 529 2079 or visit vacations.aircanada.com/en/travel-advisories
  

Cancelling your plans

• If you'd prefer to no longer travel, you can cancel your ticket.
  
• If you purchased a refundable fare, you'll receive a full refund. Depending on the type of ticket purchased, a cancellation fee may apply.
  
• If you purchased using Aeroplan points, you can cancel your flight and redeposit the points into your account.
  
• If you purchased a non‑refundable fare, you may cancel your itinerary and receive the value of your ticket in your AC Wallet or as a Future Travel Credit to use on your next Air Canada booking.
  
• You could also choose to do nothing and see whether your flight is cancelled by Air Canada, in which case you will also have the option to be refunded (see below).
  

Keeping your current flights

• If you choose to keep your current flights now, and a work stoppage does occur, please be assured that you will be notified by email or text.
  
• We will work to support our customers by rebooking them with the best available options, but space will be limited.
  
• If your flight is cancelled by Air Canada, you will then be eligible for a full refund regardless of your fare type; furthermore no cancellation fees will apply.
  

More details for customers are available at aircanada.com/action and for Air Canada Vacations customers at vacations.aircanada.com/en/travel-advisories.

Thank you and we appreciate your flexibility and consideration of these options.
