Thank you for your feedback. The 60% off refers to how much you could save by pre-booking your parking, as opposed to paying the gate price at the airport. I can see from our system that you were able to make use of our current £10 off offer, which is great. For further information on our current offers, please don't hesitate to contact us directly and one of our customer service team members would be more than happy to assist you. We hope you enjoy your trip!
