Simply amazed that $300 RT ticket prices were not sustainable. (Yes, Sarcasm) When you lose money on every ticket, there is no making it up in volume...unless you drive everyone else out of business then jack the prices.
However, not a concern for me, never flew them, in Iowa, not near one of the airports they used. We also refuse to drive to one of the major hubs to save a hundred Dollars or even more, time and driving (and hotels, and food, and parking) has a cost, and the last thing I want on return after a trip and a long flight, is to hop in a car and drive another 4-6 hours. I'll stick with Delta and fly out of my local airport.
