What is the role of the Department of Transportation (DOT) in relation to ACAA?

The Department of Transportation (DOT) plays a critical role in enforcing the Air Carrier Access Act (ACAA) by ensuring that air carriers comply with regulations designed to protect the rights of individuals with disabilities. This involves investigating complaints filed by passengers who believe they have faced discrimination due to their disability or violations of the ACAA's provisions. The DOT's responsibilities also include monitoring airlines for compliance and imposing penalties for non-compliance, thereby serving as a regulatory body that safeguards the rights of disabled travelers in the aviation sector.

The other options relate to activities that are not within the scope of the DOT's responsibilities regarding the ACAA. For instance, providing funding for airline upgrades does not align with the DOT's function under the ACAA. Similarly, creating awareness campaigns for passengers may be part of broader consumer education efforts, but it is not specifically tied to the enforcement of the ACAA. Regulating airline ticket prices falls under economic regulations and is separate from ensuring accessibility for individuals with disabilities. This clarity underscores why the DOT's enforcement and investigative role is pivotal in upholding the standards set by the ACAA.
