All of the above posts may have been somewhat true at one time but do not apply anymore.
I worked there from 98 to Feb '01 and can tell you it was one of the best places to work as far as "bottom-feeder" cargo airlines is concerned.
They used to require a 2 year training contract if you were hired into the 3rd seat. No, more... Paid me back all the money they took plus interest. Also, they stopped hiring captains off the street and lots of guys went from FE to Captain in 3-4 years.
Upgrade was about 1-2 years to from FE to FO and everyone had a fair shot regardless of your flight time.
Work rules were put into effect when management feared the Teamsters would come on the property and everyone got a substantial raise...I started at $30/hr and was at $48/hr a year and a half later, with a 60hr guarantee. Compare that to a regional.
You could either fly your butt off out in the Caribbean but be home after every flight, or fly the "easier" Domestic routes in and out of Dayton, OH and be based at one of several locations, hotel and car rental paid for with a two-on two-off schedule, and weekends off... 15 to 18 days off per month.
We had 12 727-200's (now only 5 or 6) all with the exception of 2 were GPS equiped and had the more powerful -15 or -17 engines
and about half of them had the "quiet wing" conversion.
It wasn't a bad place to work! I've tried to go back, but now they are not growing and therefore no one is going anywhere, especially in this economy.
