Quick video recorded on my car DVR. How to get to London Luton Airport, Long Stay car park. At the time, the short stay was restricted so this was cheap and ideal as it was free for 1hr then £1 for second hour.
The transit bus at 04:35 is the one that takes you to the terminal building, takes about 5-9 mins with no traffic. There are 6 stops inside the car park.
