I know I am late, and I would expect that most of the OP's questions would be answered by now after three months on the job.
I am curious though, is Delta still using an outfit called "Intex" to handle some ground ops? I worked for them in the 90s as a "ramp agent" at SDF for Delta. We were the most used, abused and underpaid rampers on the field. Three of us plus a supervisor trying to load and push out three planes within about 30-45 minutes every morning. Just around the corner from us, Northwest had what seemed to be 20 rampers all over 1 aircraft.
Same deal at the mail sort every night: All airlines with mail contracts show up at the mail house. Us: no less than three baggage carts, sometimes had to go back for another one, busting our humps from the time the sort started until it stopped. Everyone else: one or two carts, Northwest: no carts, one F150 tug with A/C, and two rampers to pick up a single bag of mail.
Ironic for me now that NWA and Delta are the same, so I am sure the ramp situation is/has changed.
I hope things are better than they used to be. I know as far as pilots are concerned today, Delta is the holy grail of airline jobs, but I know my opinion of them back then was far from that.
Just a curiosity. I have been away from ground ops for awhile. Worked for Brown for awhile, but that is a different world entirely, so much they put us on the other side of the airport.
