An Air Canada travel voucher is a form of compensation or credit issued by Air Canada that can be used towards the purchase of flights, services, or other travel-related expenses offered by the airline. Travel vouchers are often provided to customers as a result of flight cancellations, delays, or other disruptions, or they can be offered as part of promotions or compensation for various reasons.

Here's some general information about Air Canada travel vouchers:

• Issuance: Travel vouchers are typically issued by Air Canada in electronic form, and the voucher details are provided to the recipient via email or through the Air Canada website.
• Value: The value of the travel voucher can vary based on the circumstances for which it was issued. It could cover the full or partial cost of a flight or service, depending on the situation.
• Redemption: Travel vouchers usually have an expiration date, and they can be redeemed when booking flights or services on the Air Canada website or through other eligible channels.
• Restrictions: Travel vouchers might come with certain restrictions or terms and conditions. These could include limitations on which flights or services the voucher can be applied to, blackout dates, and specific booking procedures.
• Transferability: In some cases, travel vouchers may be transferable to someone else, but this can also depend on Air Canada's policies and the specific terms of the voucher.
• Combining Vouchers: Depending on Air Canada's policies, you might be able to combine multiple travel vouchers for a single booking, which could be especially helpful if you have more than one voucher.
• Refunds: Travel vouchers are typically non-refundable, meaning that if you don't use the full value of the voucher in one booking, you might not get the remaining value refunded in cash or another form.

It's important to read and understand the terms and conditions associated with the specific travel voucher you have received from Air Canada. If you're unsure about how to redeem or use your travel voucher, you should contact Air Canada's customer service for assistance.

Keep in mind that airline policies and procedures can change over time, so for the most accurate and up-to-date information about Air Canada travel vouchers, I recommend checking directly with the airline or visiting their official website.
