Mama,
Maybe the Dash 8s are leased from CHC or Heli-none at rip-off rates
. Are you sure Aero won't just get rid of them and lease in from a company with more reasonable rates like Arik do? CHC has been tearing the behind out of Aero ever since they took over and maybe Aero can do a damn sight better without 'help' from CHC in this respect?
