Also, "ER" is a Boeing term. Not just for Delta.
Really? Because I was once told that Boeing never made an ER 757. In fact over on FI I've read members over there teasing "the General" about how DL refers to their category as ER.
Words about arrogance, over compensating and ego were used about DL pilots and their exclusive "ER" category.
