Discount codes

We recently made changes to our discount code system, so we’ve put together some frequently asked questions to help you out.

Unfortunately, no, you will not be able to. The codes provided are valid for new bookings only.

"The coupon code entered is not valid for your selected itinerary. Please double check the offer details and try again.”

There are multiple reasons why your coupon code may be deemed invalid. They are:

  • The coupon code entered may not exist or was entered incorrectly. A common mistake is entering a "0" (zero) instead of the letter "O", entering a "1" (one) instead of the letter "I", or vice versa. Also, you may want to confirm that the code you’re entering is a WestJet discount code.

  • The coupon code may have certain blackout date restrictions. Please check the eligible travel dates for your code and try again.

  • Some coupon codes are only eligible for use on one booking and cannot be combined with another coupon code from a different or expired offer.

  • The coupon code you are using may only be valid for one guest.

  • If your coupon code is a limited or one-time use code, it means you cannot use it for more than one booking.

  • If you are booking with WestJet dollars, you may not have enough WestJet dollars in your account to make this purchase. Minimum redemption rates apply, visit for more information.

  • Your coupon code cannot be used because the code has expired. When available, you can refer to the original offer details for the expiry date. Please note; we are not able to extend the expiry date on discount codes.

No, discount codes are not valid on WestJet Vacations packages or group bookings.

It comes down to the type of code that has been issued. WestJet issues two types of discount codes: unlimited-use and limited-use; each of these works slightly different.

Let's define them for you:

Unlimited-use code: This type of discount code is usually a public offer made available to anyone, and can be used an unlimited amount of times if the flights and fares are available at the time of booking. WestJet dollars can be used when booking with unlimited-use codes.

Limited-use code: Sometimes, we have an exclusive offer with a unique discount code that is limited to a specific audience and/or quantity restriction. This code can only be used for a specific amount of bookings. WestJet dollars cannot be used when booking with limited-use codes.

If you want to confirm that your discount is unlimited-use and can be combined with WestJet dollars, here's what you do:

  • First, sign into your WestJet Rewards account. You can do this at any time by selecting the "Sign in" icon at the top right of
  • After you've signed in, go to the discount code landing page.
  • Then, there will be a booking window near the bottom of the discount code landing page. Fill in the applicable discount code and select your travel details in the booking window, then select the "Get flights" button.
  • If you are eligible to use the code based on the flight details you have provided, a message will appear at the top of the page letting you know that your discount has been applied.
  • The discount will be reflected in the prices displayed.
  • Once you reach the "Payment" step, you will have the opportunity to apply WestJet dollars to your booking.
  • If WestJet dollars are sucessfully applied to your booking, then you'll know that you're using an unlimited-use code.

Please note: Minimum redemption rates may apply when booking with WestJet dollars.

After you’ve entered the codes and selected your flights, check marks will appear beside the fares that apply to your discount code. Once you select your flights, your savings will automatically display in the payment summary on the right hand side. If you’re booking with WestJet dollars your payment summary will display that a discount has been applied, but the total savings amount will only appear in the final payment stage. If your itinerary includes any blackout dates (refer to the specific details of the offer), the discount amount displayed will only be for the portion that is eligible.

Yes, you can perform as many searches for flights as you like in order to view your options and the discount amount. The discount code will not be officially used until payment is applied.

Discount codes expire at 9:59 p.m. Mountain Time on the "book by" date given unless otherwise indicated.

Coupon and promo codes are like paper - if they are lost, they are not retrievable.

Yes. Discount codes are only valid on flights marketed and operated wholly by WestJet, and are not applicable when travelling with our code-share, interline or other airline partners. WestJet operated flights are indicated as "Operated by WESTJET", "Operated by WESTJET ENCORE", or "Operated by WESTJET LINK BY PACIFIC COASTAL" during your fight search. Other flight restrictions may apply, such as restrictions on applicable fare class (e.g. only applicable to Econo fares). This will always be noted in the discount code details.

Blackout dates are specific to the offer for each discount code. Refer to the individual discount code details to confirm whether it has blackout dates.
