You would think at some point smaller airlines would learn not to stockpile their management ranks with alumni from, as Dick Gephardt would say, miserable failures. Allegiant, perhaps as a result of its move to Las Vegas, is hiring several former National Airlines executives who were at the forefront of that operationally challeged and fiscally disasterous airline. Why is the vision so narrow and the imagination so weak that these airlines don't broaden their management horizons (not to mention the skill set) rather than continue the inbreeding of the weakest links in the food chain?
