Many people have done just that in the past. Try googling Luton Airport Parkway car park review. I can see the roof of the car park as I drive up the A1081 and there is always plenty of cars parked up there 24/7.
I have been spouting on for years that this is where the clever people park. A weekly ticket is £34. Don't forget to buy a return shuttle bus ticket from the conductor of the bus for additional savings and be prepared to be squeezed into a shoebox if you end up on the standard single decker bus as they have 2 of them.
