At current oil prices, several large and small U.S. airlines will default on their obligations to creditors beginning at the end of 2008 and early 2009, according to a study issued by AirlineForecasts, LLC and the Business Travel Coalition. The study shows that $130/barrel oil prices will increase yearly airline costs by $30 billion, while airlines will be able to generate only $4 billion in fare increases and incremental fees. The implication of this alarming trend is that several large and small airlines will ultimately end up in bankruptcy, and of those, some will be forced to liquidate.
