Booked this parking for the first time recently and paid using a credit card on-line. Was not quite sure what to expect on arrival at the airport, but the system worked faultlessly. I took a parking ticket for the short term car park, proceeded to the Priority Parking barrier and re-inserted the same ticket to gain access. This ticket was then returned. On my return, this same ticket allowed me to exit the car park very easily - no further charges being requested. I will certainly use this parking again, albeit slightly expensive, but for 24 hour periods it is excellent.
