This is probably the 10th time I've had it happen to me, but when I went back to check the PALL list of a flight I was on from PIT-PHL yesterday, I was listed as an S4! All because I still have a my MidAtlantic travel card. For some reason agents list me as an S4, and have even been listed as an S5 before. I also know other agents I worked with at MDA who have had the same problem. On one instance I didn't get on a flight because of this, and I know of others who have experienced the same. All of us who used to work the ramp at MDA are still waiting for our new plain US travel cards, but they haven't seemed to show up yet.
