Moreover, you don't seem to understand the purpose and process for DOT complaints. There is no requirement that a complaint be based on a "DOT violation." Even when the issue falls outside existing DOT reg, a complaint may be appropriate because:

1. It helps DOT identify problem areas for future regulation.
2. It adds to the published complaint statistics.
3. It will be forwarded to UA for response, and will receive higher level attention than if made through the normal customer care channels.
