" we believe the operating losses on the remaining ERJs and E190 in service at Frontier and the grounded RJs will more than offset the profits of our fixed fee flying. Of course this transfer of risk between the business segments does not affect the consolidated result, but it does mean that Republic will have to reconsider how much flying it may want to continue to perform under the Frontier codesharing relationship."
