Well you are partly right. Delta has been shrinking CVG and Comair has been bearing a disproportionate brunt of that. Comair is more reliable (as is everyone else) compared to Mesa. Comair isn't going to JFK because they intend to grow it, they are going because Mesa/Freedom wouldn't cancel their flights to allow Delta to take the slots when delays hit (almost every day) Comair (and soon Mesaba as well) as wholly owneds can't tell Delta no when the call comes to cancel flights at JFK. That's the big reason Freedom is being swapped with Comair. Any growth at JFK will come when Mesaba is moved out of SLC and into JFK.
