And if their plane maintenance is any indication Delta runs one of the premier maintenance outfits (Delta TechOps) globally. About a quarter of their TechOps business is for outside airlines. So sure if that's any indication their application architecture is probably pretty decent (it's not). This was an ETOPS flight, yeah? Those come with higher standards for crew training, maintenance, and minimum equipment per the FAA. I wouldn't worry until/unless the FAA starts making noise about revoking Delta's ETOPS certification (which would hurt their ability to fly a bunch of routes and their ability to perform maintenance for e.g. Hawaiian).
