None of the traditional six network carriers are expecting to be cash flow positive for the 1st quarter.

If the frequent flyer changes were driving so many passengers to other carriers, why are all the other carriers doing so poorly? Given DL's size and the number of high revenue FF'ers they are driving away, the other carriers should be seeing some real improvements. Yet, every carrier continues to miss revenue targets. I guess they must all be flying JBLU,WN and AAI.
