WestJet Promo Codes & Coupons September 2025

If your WestJet promo code isn’t working, it’s usually due to issues like code expiration, ineligible routes or dates, or not meeting specific fare or booking requirements. Common error messages include “Invalid code,” “Code expired,” or “This code cannot be applied to your booking.”

WestJet promo codes often have strict rules: they may only be valid for certain destinations, travel dates, or fare classes, and can’t be combined with other offers or used more than once per booking. Codes must be entered exactly as shown, and are typically case-sensitive. If you see an error, double-check the code for typos, ensure your booking matches the promo’s terms (such as eligible travel window or fare type), and confirm the code hasn’t already been used or expired. Some codes are single-use or exclusive to specific groups, like conference attendees.

Pro tip: Always review the promo code’s terms and conditions before booking, and try codes early in the checkout process to catch errors before payment.

You enter your WestJet promo code during the checkout process, after you’ve selected your flights but before you complete payment. Look for a field labeled “Promo Code” or “Discount Code” on the payment page.

Here’s how it works:

• Select your flights and proceed to checkout.
• On the payment page, find the promo code field.
• Enter your code and click “Apply.” If valid, you’ll see the discount reflected before finalizing your booking. If the code is invalid or doesn’t apply to your booking, you’ll receive an error message and the discount won’t be applied.

Pro tip: Copy and paste the promo code to avoid typos, and always confirm the discount appears before submitting payment.

No, WestJet promo codes generally cannot be applied to existing bookings. They must be entered during the initial booking process, before payment is completed.

Once a booking is finalized, there’s no option to retroactively add a promo code or discount. This is a common restriction across most airlines, including WestJet, to prevent misuse and ensure codes are only used as intended.

Pro tip: If you forgot to use a promo code, consider canceling (if your fare allows) and rebooking with the code, but check cancellation fees and fare rules first.

Yes, WestJet promo codes always have expiration dates and often come with additional restrictions, such as valid travel periods, eligible destinations, or specific fare classes. For example, a code might only apply to flights booked by a certain date, for travel within a defined window, or only for certain routes or fare types like Econo or Premium.

Codes may also exclude taxes and fees, apply only to base fares, and cannot be combined with other discounts or used on partner-operated flights. Always read the promo’s terms carefully to ensure your booking qualifies.

Pro tip: Check the promo code’s fine print for blackout dates, eligible routes, and booking deadlines—set a reminder to use the code before it expires.
