A) SWA-AirTran was a decided without an arbitrator. It would be hard to include that as evidance in a an arbitrated SLI.
B) What is shocking and even more so disappointing, is seening LUAL and LCAL guys proposing a SLI that would include all the things they hated about the CAL-UAL SLI. Again it is all about "me", and not about what is "right" for all while setting an example of being professional.
