The preponderance of indicators show that the world is undergoing a protracted, if wobbly, recovery.
As the economy (slowly ... slowly) grows and (Don't screw it away, Europe!) gathers steam, I expect mature companies like Delta to grow along with it. Combine that with the fact that we're getting tantalizingly close to that $10B debt number, and I think our seniority list will grow, not just turn over due to retirements, over the next ten years.
