They seem to be around the same levels as most other airlines. As low as 400-500 hours. If you have 1000/100 you can drop your stuff in and get called off the street. Lower time pilots will need some extra multi or have thier resume submited through a bridge program. I think the lowest I have seen was mid 400tt and about 130me.

Good Luck

PS, COMAIR is hiring in the high 200tt and 100ME,
