The ticket excise tax is just that..a tax. Generally its used as FAA funding..and PFCs are supposed to be "lock boxed" for airport development...but we all know how well those lock boxes work.
Airlines are one of the highest taxed and most regulated "deregulated" industries we have. (jet fuel and payroll are 2 highest expenses...both taxed) and the revenue taxed at 10% before you get to the special security fees, etc.
Combined with their cutthroat pricing model, its not much of a surprise that they don't earn profits.
