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.

Yes, you can book through using both your discount code and WestJet dollars. Before you begin booking, make sure you've signed into your WestJet Rewards account. You can do this at any time by clicking the "Sign in" icon at the top right of After you've signed in, go to the discount code landing page. There will be a booking window near the bottom of the discount code landing page. Simply fill in the applicable code and select your travel details in the booking window, then click the "Get flights" button. If you are eligible to use the code based on the details you have provided, a message will appear at the top of the page letting you know that your discount has been applied and the discount will be reflected in the prices displayed. When you are in the "Payment" step of the booking flow you will then have the opportunity to apply WestJet dollars to your booking. 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 (ie. code-share, interline or other airline partners). WestJet operated flights are indicated as "Operated by WESTJET" 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.
