Pros
I have worked with Delta several times over the last 5 years, as a consultant and for the last 2 years as an FTE. Delta has been professional and accommodating. The corporate staff respond when needed, and has maintained a culture of camaraderie and access. There are great opportunities for growth and a substantial pool of knowledge willing to help and, in the last year, significant changes have allowed very competitive benefits. A great place for those who prefer to challenge themselves and to work in a world larger than a desk.
Cons
Not as many location opportunities as larger companies, but mitigated. Larger companies will likely constrain your experience to fewer rolls so there is a trade off. They are growing and with that are the normal issues of growth but they are managing that much better than many other companies I have consulted for, regarding both organizationally and people. So I would anticipate more locations and the opportunity for a broader experience in the near future.
