Earlier Tuesday, Motley Fool Stock Advisor pick JetBlue Airlines (NASDAQ:JBLU) released earnings for the second quarter ended June 30.

  • While higher salaries and increased fuel expenses didn't prevent margins from rising, new CEO Dave Barger offered a warning that the soft operating environment will make it tough for JetBlue to continue its current performance.
  • Management is taking action by deferring deliveries of 16 Embraer (NYSE:ERJ) 190 jets to 2015 from 2013, which, in turn, should slow capacity growth.
  • Heavy summer traffic created extra congestion, causing JetBlue's on-time performance to slip to 69% from 77.9%.
  • Will that be enough? The 759 amateur and professional stock pickers following JetBlue in our Motley Fool CAPS investor-intelligence database don't seem to think so. They give the stock just two out of five stars.
