Interestingly, they're not out yet. Heathrow, Gatwick and Stansted, and almost all of the other big airports, have added up their figures and sent them to the CAA - but not Luton.
I seem to remember that they were also late with their figures last month - so what is going on? Is it an attempt to bury bad news - or did their calculators get buried under the "four feet of snow" that apparently affected the airport but seems to have missed all the surrounding area, which only got a foot of the white stuff?
