No, swamt, DL is not looking bad right now.
Even when WN pilots had a cockpit catfight that destroyed a fairly new aircraft, WN suffered little damage.
The public doesn't know or care about what causes accidents unless there is something of repeated or clearly malicious nature which is what happened at Malaysia.
And every indication continues to focus on the braking systems and handling of the aircraft, not on the pilot actions which the NTSB said was done by the books according to DL training which is also similar to what other carriers do in light of the AA LIT accident.
Given black box technology, the NTSB could have easily determined if the pilots screwed up but they did not provide any indication that was the case and are looking elsewhere.
