I think the Motley Fool commentaries are usually contradictory over short periods of time and are generally full of cr@p, this being no exception. Capacity discipline combined with a large network of choices has been yielding consistent profitability, and this guy expects bankruptcy? When are these big losses supposed to start? My profit sharing check screams that he's full of it.

Add to that the smart economic decisions such as...
- buying an oil refinery
- buying slightly used a/c and getting their full value over time

The biggest reason someone may choose Delta is assurance of getting to their destination on time, as in operational reliability measures.
