A few short thoughts? Really? While I would agree that SWA has been slow to react to business opportunities I am not totally sure that DAL and AT are the perfect business models that you appear to claim. As I said in the past, a few years of difficulties and a trip through BK could cure many of the issues that you point out. It certainly has helped a few airlines (sometimes twice) to fix their problems.
I will agree that the next couple of years will be interesting because the issues that you bring up must be addressed. You seem to also have some ideas that are certainly worth discussing so have at it. At this point, the employees of SWA/AT are in the same boat (I refuse to call it a ship). We turn this sucker around or we come out of BK as a force to reckon with.
