stilton,
If you care to inform yourself you would discover that all remaining 'Legacy's' are consistently profitable.
With your experience, I don't think you should count the chickens before the eggs hatch. I am sure you are aware, airline profitability follows a historic sine curve over time. The median of the curve (neutral point) falls below the average break-even of the "Legacies". There is no reason to believe that is going to change anytime soon. Consistently profitable depends on how one looks at it, by month, by quarter, by year? At the moment, the collective profitability of the "Legacy" airlines would hardly buy but a few single aisle jets, if they had to pay cash. Perhaps this will change if the collective management of the "Legacies" decide the grass isn't greener on the other side of the fence and tend to business in their own backyards, focus, focus, focus... Don't see this happening anytime soon, either.
