It is confirmed and bookable on KLM's website. Same goes for SK OSL. Double daily BHD appeared in Flybe's online timetable for a while but appears to have been an error.
Jet2 have expressed an interest in serving ABZ before when they launched their GLA base. I would hope that if ls are looking to expand then ABZ is fairly high up the list.
