This rulemaking would address a number of proposals to enhance protections for air travelers and to improve the air travel environment. Specifically, this rulemaking would enhance airline passenger protections by addressing whether to codify in regulation a definition of the term "ticket agent." The rulemaking would also consider whether to require large travel agents to adopt minimum customer service standards and prohibit the unfair and deceptive practice of post-purchase price increases. These issues, previously part of a rulemaking known as Airline Pricing Transparency and Other Consumer Protection Issues (2105-AE11) have been separated into this proceeding.
