Guy, OH was largest privately owned "Regional" carrier in the world before DL bought it (still not sure why) and screwed it up. It WAS a place to work and retire from. You'd surprised how many pilots retired from there after 15, 20, 25+ years in the line. It wrote its own ticket (per say) for a very long time, and was bigger than lots of the majors of this time (Airtran, Spirit, and I believe Jetblue). And at one time was hellbent on moving on up (to the east side) to "major" status by buying bigger aircrafts (757, 737 and others), and join the fray against the DL, US, AA, etc in this country. Btw, I believe after the purchase, there were 10-15 of the DL MD-88 that were fully purchased with OH assets (money) and for some years flew under the Comair Holdings registration. I jumpsat in a couple of those and got a kick by seeing the registration.
Please research it.....bet you it will surprise you.
