Carl,
Just look at contract negotiations over the last 10 years. Many airlines spent 5 years minimum in Sec 6. It took Pinnacle 5+ years. RAH has been in negotiations longer then that. I believe TranStates was in Sec 6 for 5+ years as well. Heck, how long was AirTran in negotiations before they brought ALPA in? How long has UsAir been in Sec 6? These are just a few examples.
I'm not saying that we will be stuck in Sec 6, but it has happened to quite a few airlines lately. Many are in Sec 6 now, & management is able to use the RLA to drag things out.
