DAL is a matrix score, IP and PIC time, GPA X Major credit, community service, check airman/NATOPS instructor, etc. It's not just one thing. I got hired with a 2.83 in Mech Engr from a major engineering school, 2500 hours 1/2 single seat 1/2 instructor. Safety officer that probably off set the low GPA. My class had others with less hours, better GPA, or same GPA easier major with more hours. They have 10,000+ apps, and haven't gone through more than about 10% at the most I would think. I think they are hiring leadership right now, because in <10 years, the guys getting hired now are going to be capt's flying with much less qualified FO's as the "pilot shortage" drives much lower minimums for hiring in ten years.
