Final rule.

The U.S. Department of Transportation (DOT or Department) is issuing a final rule codifying its longstanding definitions for the terms "unfair" and "deceptive" in the Department's regulations implementing its aviation consumer protection statute. The final rule also describes the Department's procedural requirements for its rulemaking and enforcement actions when based on the Department's authority to prohibit unfair or deceptive practices. Most of the Department's aviation consumer protection regulations, such as the Department's rules on overbooking, are based on the Department's authority to prohibit unfair or deceptive practices. This rule is intended to provide regulated entities and other stakeholders with greater clarity and certainty about the Department's interpretation of unfair or deceptive practices and the Department's process for making such determinations in the context of aviation consumer protection rulemaking and enforcement actions.
