It seems that user impressions of the UA Chat Agent is being talked about here in various threads but not a thread dedicated to it.

My use of the chat agent gets kicked off when the website or app is lacking functionality or just errors out. The biggest use of the chat is my FFCs getting into a state that it becomes unbookable or a FFC just disappears and will not show up despite using the lookup functionality ( I have not found a common theme to how FFCs get to this state ).
Side note: I learned a long time ago that DL loves to "disappear" FFCs so I keep a transaction log of all credit IDs, amounts and dates.

The UA Chat Agent rankings:
Professionalism: 10/10 - Always respectful and polite when working through the issues, No passive/aggressive or attitude issues.
Accuracy: 10/10 - The agent always confirms any transactions before executing them.
Accountability: 10/10 - One of the best things about the chat is that it instantly provides a running exact copy of the entire conversation that can be referred to at any time,
Speed: 7.5/10 - The agents might be multitasking other conversations as sometimes there is lag in the real time chat. I know sometimes they may have to talk to people that handle pricing but sometimes in normal conversation there is lag. UA is way ahead in this area compared to DL. A normal chat with UA takes around 20 minutes while DL is around 80 minutes.
Multitasking: 10/10 - I find phone conversations to be difficult to multitask, the agent may come back from a hold with me in a critical point of another topic The chat allows me to complete or bookmark my thought and then rejoin the chat.
Nice: The agent volunteers to complete my seat assignments ( small thing but it just saves me some time ).

Looking forward to hearing your experiences with the UA Chat Agent and/or other carrier chat agents.
