@Jessie and Guill: Many thanks for sharing your story, and Welcome to FT! I'm already on record that hopefully UA has provided the FA with training and counseling related to de-escalation.
I wonder whether you could answer a few more questions:
1. Did the captain ever ask your side of the situation?
2. In reflection, do you believe that you could have done anything different which would have resulted in a better outcome?
3. Are you considering litigation?
Many thanks!
