I made a booking at the mid stay car park for Saturday 13th June. I was dismayed to find when I arrived at approximately 10.30 am there were no parking spaces. I along with many others toured the car park for a space. In the end after 30 minutes I parked where it said "Staff Parking" and reported it to the office. I understand from the company overseeing the parking on behalf of Luton Airport that this is an everyday occurrence for Luton Airport to overbook. I was travelling on my own and was not a good start to my journey. I will not park there again.
