We booked our parking at Edinburgh Airport through Jet2 and paid in advance for the two weeks we would be away. On our return we exited the terminal from a different point and found a lack of signage directing us to the Long stay carpark and no staff available to assist. When we finally retrieved our car and drove to the exit gate we inserted the parking ticket in the machine and were advised that we owed £330 This came as a great shock as we had made all the arrangements to ensure a smooth parking experience. We looked for a staff member for assistance but there was no one present, finally we managed to contact an operative via the intercom who asked for the booking reference number which fortunately we had to hand and were able to quote this number so we were allowed to exit the car park. Surely this should have been unnecessary as we had the parking ticket and had pre booked so the system should have picked up our booking and not asked for additional payment. We also wonder what would have been the outcome had we not kept the booking reference document with us.
