So I am here sitting in Memphis because I missed my flight to Detroit. Here's the rant, please let me know what you think.

I signed up for a MEM-DTW flight via Travelnet with my S3C priority. I went to the gate one hour prior and asked the GA if anyone had signed up for the jumpseat and if not if I can sign up because it didn't look like I'd make the flight. She told me that no one had signed up but it's fine because it looked like I'd make it. So in the meantime an OAL jumpseater signed up for the jump and got the JS. I finally get my boarding pass for the last seat in the airplane. Low and behold, after I'd just finished stowing my bag, flightcase and buckled up, I get pulled off the flight because of a late passenger (of course). I'm not trying to sound entitled or anything but is there something I could've done differently? Also apparently you can't sign up for the jumpseat if you're listed on Travelnet. Has anyone run into a similar problem?
