Simply put: Airlines have no compelling reason to offer any breaks. Planes are full. Investors want a payout. And new planes are on order.
In fact, fares are going higher. And those bag fees that airlines instituted in 2008 when fuel prices spiked aren't going away either.
In the 12 months ended in September, U.S. airlines saved $1.6 billion on jet fuel. That helped them post a 5.7 percent profit margin in the first three quarters of this year, robust for the industry but lagging behind the 10 percent average for the Standard & Poor's 500.
In the past six years, airlines have done a great job of adjusting the number of flights to fall just short of demand. As a result, those who want to fly will pay a premium to do so. Airlines are selling a record 85.1 percent of their domestic seats. Thanks to several mega-mergers, four big airlines control the vast majority of flights, leaving very little room for another airline to undercut fares.
