Air Transat Promo Codes & Coupons February 2026

An "invalid code" error usually means the code has expired, doesn't match your booking details, or you haven't met the minimum booking value requirement. Air Transat promo codes are time-sensitive—many expire within days of being released—so even a correctly copied code won't work if its expiration date has passed.

Before assuming the code is broken, verify these things:

1. Check the code's expiration date on the promotion page where you found it.
2. Confirm your booking meets any restrictions—some codes only work on selected flights, specific routes, or certain cabin classes.
3. Ensure you've reached any minimum booking value if one applies.

If you're still getting an error after checking these, the code may have reached its usage limit or been deactivated by Air Transat. Try clearing your browser cache and cookies, then attempt the code again in an incognito window, as cached data sometimes causes checkout errors.

Pro tip: Use SimplyCodes before booking to verify codes in real-time and see exactly which flights and dates each code works for, saving you the frustration of discovering incompatibility at checkout.

This means your code has restrictions limiting it to specific destinations, departure cities, or travel dates, and your selected flight doesn't match those parameters. Air Transat frequently runs targeted promotions—for example, a code might only apply to flights to Portugal or departures within a certain date range.

When you see this error, check the promotion details carefully. Look for language like "selected flights," "select destinations," or "valid for departures between [date] and [date]." Some codes are sitewide, but most Air Transat promotions target specific routes to maximize their marketing impact. If you're flexible on dates or destinations, try adjusting your search to match the code's restrictions. If you're set on your original flight, browse available codes on SimplyCodes to find one that actually covers your route and dates.

Pro tip: Before selecting your flights, scan the current promotions list to see which routes and dates have active discounts, then build your booking around those parameters rather than trying to force a code onto a flight it wasn't designed for.

Unfortunately, you cannot apply a promo code after completing your purchase—Air Transat requires you to enter the code during the checkout process before payment. Once the transaction is finalized, the discount window has closed.

However, you're not completely out of options. Contact Air Transat's customer service to explain the situation; while they don't guarantee retroactive discounts, they may issue a travel credit or refund if the code was legitimately available at the time of your booking and you can demonstrate you attempted to use it. Keep documentation of the promotion (screenshots of the code and its terms) to support your case. Some airlines honor goodwill adjustments, especially if the error was on their end. Alternatively, if your booking is far enough in the future, you could cancel and rebook with the promo code applied, though you'll want to check Air Transat's cancellation policy first to avoid losing money on fees.

Pro tip: Always apply your promo code before clicking "confirm purchase"—take an extra 30 seconds to paste it in the designated field on the flight selection page and verify the discount appears in your total before proceeding to payment.

No, Air Transat does not allow stacking multiple promo codes on a single booking. You can only apply one code per reservation, so you'll need to choose which discount provides the best savings for your specific flight.

When you have multiple codes available, compare their actual dollar or percentage value against your booking total. A 25% discount on a $400 flight saves more than a $100 flat discount, but a $654 off promotion might beat both depending on your total fare. The checkout system will only accept one code, so entering a second code will either replace the first or generate an error. Some airlines allow combining promo codes with loyalty program discounts or military benefits, but Air Transat appears to treat military discounts as a separate category rather than stackable with standard promo codes.

Pro tip: Calculate the actual savings from your top 2-3 available codes before checkout, then apply whichever one gives you the biggest dollar amount off your total fare.

Air Transat promo codes typically work on flights, but their compatibility with already-discounted fares or vacation packages depends on the specific code's terms. Some promotions explicitly state they apply to "selected flights" or exclude sale fares, while others may work on top of existing discounts.

The safest approach is to check the fine print of the specific promotion you're considering. Look for exclusions like "cannot be combined with other offers" or "valid on base fares only." Vacation packages (which bundle flights with hotels) sometimes have their own promotional codes separate from flight-only codes, so a flight discount code might not apply to a package deal. When in doubt, add the code during checkout and see if the system accepts it—Air Transat's system will reject incompatible codes rather than silently ignoring them, so you'll get immediate feedback. If it doesn't work, try searching for a vacation package-specific promotion instead.

Pro tip: If you're booking a vacation package, search specifically for "Air Transat vacation package deals" rather than flight codes, as these often have better bundled discounts than trying to layer a flight code onto a package.
