Used the LSCP in August/September 2015. A truly shocking experience. Number plate recognition recorded the wrong number plate on the ticket. And then, on return, a terrible 45 minute wait for a bus from the terminal back to the car park. (Some in the queue had been there longer) And this was mid-afternoon. Thankfully it wasn't cold or raining because there's no adequate cover while your life passes by. The queues were huge and many failed to get on the bus at all! This meant that it was utter chaos at the car park bus stops as nobody could get off past the stacked up luggage. My advice - choose a different airport. Anywhere but Luton. Total rip-off, bad, bad service.
