Refund Policy

The SkyMiles may take up to 24 hours to process your refund. Once processed, your bank will take care of the rest. Just know that it may take them up to 7 days to post the credit to your account, and up to 2 billing cycles to show the credit on your statement. The refund will be processed back to the original form of payment. So, if you have paid using your debit/credit card -- that’s where the money will be refunded.
If your credit card statement includes a charge from a third party (such as a low-cost airline, rental car company, or cruise line), you’ll receive your refund from them, not The SkyMiles . If this is the case, get in touch with that third party to ask any questions about refunds. In case of a partial payment or deposit, the refund will be processed after the deduction of applicable fees and charges.

For bookings made through points/credits.
In the cases of cancellation of bookings that are made through points/credits,the applicable cancellation fee will be deducted from your points balance.
If you used points and a credit card to pay for your booking, any cancellation fees will come out of the points portion of your refund first, followed by the credit card portion, if necessary.

Flights
In case of cancellation within 24 hours, only refundable bookings are eligible for a full refund.
For non refundable flights, you may get a flight credit to use for a future booking.

Hotels
Most hotels refund all your money if you cancel before their cancellation deadline.
Some hotel rooms are non-refundable, meaning you won’t get your money back if you cancel.
If you cancel a non-refundable hotel booking, or cancel your booking after the hotel's cancellation deadline, you won’t be able to get a refund, no matter how you paid (using points or your credit card, for instance).
If you canceled before the hotel's cancellation deadline but still see a charge from them on your credit card statement, get in touch with the hotel itself to make sure you get your refund.

Vacation Packages
If you booked your package:
Within the last 24 hours: You may be able to cancel and get all your money back.
More than 24 hours ago: Your airline, hotel, car rental company, or activity provider may have a cancellation fee that we’ll pass on to you.

Cars
Does your prepaid car booking qualify for a refund? Check out your itinerary for details. If it does, just know you have to cancel the booking at least 6 hours before pick-up.
Need to return the car early? In this case, you won’t be refunded for any unused time.

Cruises
Most cruise bookings are eligible for a full refund if you cancel up to 90 days before departure.

Activities
You can get a refund for most activity bookings if you cancel before the activity's cancellation deadline. Just keep in mind that some activities are non-refundable.
