I've had great SkyClub agents help my wife and I figure out how to get a new international flight after our connecting flight was so delayed we were going to miss it. Great help!

And they also give you the "real deal" usually on your upgrade chances, which is great.

And once, we asked about our chances, were told we probably wouldn't get it, but apparently were nice enough to the agent that she gave us (without us asking for anything) a couple drink tickets since she knew we were going to be stuck in coach for about 4 hours... (SAN-ATL)
