Thanks 1KHI! I think it's a great idea to list the set of issues UA employees are struggling with.
Here's one I was shocked to death:
5) Reinforce agents how to add to customers to standby list for connecting flight. Happened to me Today at JFK United club. Flying JFK-LAX-SAN. Agent was unable to put me on standby list for earlier connecting flight LAX-SAN. She tried typing SDC, etc and nothing (of course SDC didn't apply since fare class was not open, thus getting an error).
