Not so far as I know - still very expensive I believe.
The place has been incredibly badly run for years (good staff, dreadful airport director) - a new airport director has taken over recently and actually does seem to be doing a good job, but he clearly needs to raise some funds to change a few things, so I'd not hold your breath about an early reduction. The based schools there are also complaining about significant increases in what they're paying.
Only a place to go if you have a reason to be at Cranfield to be frank.
