It used to be - but this flight is AY mainline. They recently introduced four-digit flight numbers for some European flights - for those flights that overnight at their destination instead of an immediate turn around. MAD is one of these, as are the late night flights to places like CDG and LHR. The change seems to be effective with the winter schedule 2009-10.
