From a Comair mate asking about CX after a presentation a few days back.
CX suggested to DEFO candidates with a lot of experience - Comair pilots in this case - a fast track career to command based on experience.
I have also heard this has been said to ex Dragon CNs rehired as DEFOs.
So, after the fast track SO to FO upgrade out of seniority, here comes the fast track command upgrade out of seniority.
