Frontier Airlines has had one of the most topsy-turvy histories of any airline, and its first-quarter earnings report was no exception. Sporting a wild animal on each tail, the airline has been soaring in recent years.

In 2017, Frontier had the seventh best operating profit margin in the world. But something happened in Q1 2018, as its margin was cut in half. Meanwhile, Air France/KLM searches for a CEO. Also, how important is it that United Airlines—by a wide margin—gets more revenue from Asia than Delta and American? Norwegian continues to lose money and remains, for the moment, without a buyer to bail it out. But at least Norwegian isn’t Fastjet, which notched a negative 55% operating profit margin in 2017.
