I do not have a problem with NWA, But their DC9s are O L D no matter how well they are maintained. It is time to go. Hawaiian has already retired their -50s in favor of the 717, and NWA still has the second oldest DC9 built. Look at how much Hawaiian has saved on costs since aquiring the 717. They have saved a bunch of money. The NW DC9s may be paid for, but they will save money with the 717s in the long run. Those DC9s are too old, and have to be maintained alot which costs extra money. The Dispatch Reliability on the 717 is inherent in any new plane. There are still a few bugs to be worked out like the APU Problems. (Causing most of the delays). Do you remember when the 717 first came out, the engines were causing problems. Now that those are fixed, they have to fix the APU problems and voila. So I would rather fly on a 717 than a DC9, because the DC9 is old, smelly, and LOUDDDDDDDDDDDDD. The 717 is New, 100% Fresh Air, and QUIIIIEEEEEEETTTTT. You do the math, Passenger comfort, and safety comes to mind at AirTran while at NWA, MONEY comes to mind.
