Airlines have been reducing costs, cutting capacity and looking to ancillary fees to survive the economic downturn. JetBlue, for example, has been expanding its ancillary fees, enabling the carrier to generate additional revenue. "When we combine all of our ancillary revenue reported in the passenger revenue line with those in the other revenue line, our total ancillary revenue increased about 10% year over year in the second quarter, to about $17.50 per passenger," said CEO David Barger.
