If you have cancellation cover, you're free to cancel or amend your booking up to 24 hours prior to your arrival at no cost. So for a cancellation, you'll receive a full refund for no additional fee.

Whether you receive a refund for canceling airport parking depends heavily on the specific booking terms and the timing of your request. Most major airports and third-party parking operators allow for a refund if you cancel at least 24 hours before your scheduled arrival time, though many will deduct a small administrative or cancellation fee (often around $10 to $15). However, if you have booked a "non-refundable" or "saver" rate, you are generally ineligible for any money back regardless of when you cancel. Some premium services offer "cancellation protection" for a few extra dollars at the time of booking, which guarantees a full refund up until the last minute. If you simply don't show up without notifying the operator, or if you try to cancel after your start time has passed, a refund is almost never granted. It is also important to note that if you booked through a third-party aggregator like Expedia or Looking4Parking, you must handle the refund through them rather than the airport itself. Always check your confirmation email for the specific "cancellation window" to ensure you don't miss the deadline.
