I agree - on both legs of my trip to and from Tampa a few weeks ago it didn't clear when it was supposed to . The most annoying thing was that when I called, two 1K agents said that I was waitlisted yet when I logged off and back on I was still listed as "pending." I called again and only with the third was told I don't know what happened and was somehow finally added to the waitlist. The First class cabin had 2 people in it when I looked on departure and then was nearly full when I was waitlisted. I asked to speak to a supervisor to see what the problem was and to see if others (since I didn't notice this until I checked in - within the 24 hour window) in a lower tier had been upgraded. Shocker - they couldn't tell! Although there is no excuse for electronic processes not working, what is completely unacceptable is the constant incompetence that you get even with the 1K desk. Is it really acceptable that a common mantra is "call back and try another agent for the correct answer?"
