Pros
Great travel benefits and for the most part great people. Policies and procedures were very clear and generally there were plenty of resources to make work easier. I felt that I had a decent work/life balance, which can be hard to find at an airline.
Cons
The company is extremely anti-union. While I don't believe that unions are needed in every work setting I felt that Delta's extreme disdain for unions was a bad sign. I worked for Northwest Airlines previously and became part of Delta through the merger. What I found was that at Delta there was propaganda EVERYWHERE to indoctrinate employees into managements ideology. I feel that a company that respects the rights and intelligence of its workers doesn't try to manipulate how they think and feel. Other airlines, such as Southwest, have a long tradition of respect for their workers which is reflected in their willingness to work with unions. If you decide to work here, keeping a low profile is best.
