...ACARS data has not been leaked yet!
Safety and quality depend on adhering to standards and procedures. There is a good reason why the LH group is respected on both, despite this sad event.
However I'm not sure ACARS data exist. The prime purpose of ACARS is to provide maintenance data so engineering may prepare to rectify a fault when the plane lands. This makes sense on longhaul flights, but makes little difference with stage lengths under 2 hours. As ACARS costs money to install and operate, its benefits must outweigh the costs. 4U works on the low cost model, I'd be very surprised if they would have ACARS. In the outfit I used to be with, we only had it for the longhaul fleet for above reason.
