Hello.

Seeking advice
My background :ATP , mostly light aircraft , some flight instruction and presently I fly as a first officer on a corporate Citation 500.
About 20 years ago I flew a private B727 as a second officer and logged 650 hours on the panel.
With all the hiring these days I was wondering if anybody could list the pros and cons of choosing AD HOC cargo airlines ( DC9 MD80 B727 B737) or a position with one of the regionals carriers .( EMB or CRJ)

Cheers.
