Currently heading ATL-DCA. The captain Came out and greeted everyone and let everyone know that those of us seated in first are the top 5% of their flyers and we make 85% of the complaints. Thanked us continually for flying delta and said to let him know personally if we weren't happy with anything. He said if it wasn't something he could fix he would help write it up and send it to Richard Anderson. He had a great attitude that was very welcoming. Delta needs more pilots like this!
