Which aspect does the DOT focus on regarding aviation?

The primary focus of the Department of Transportation (DOT) in aviation is on ensuring adherence to international best standards. This encompasses a wide range of responsibilities, including regulation and oversight to guarantee safety, security, and efficiency in air transportation. By enforcing these standards, the DOT helps to maintain a level of quality and safety that is critical for all airline operations, which is essential for protecting passengers and improving overall aviation regulatory frameworks.

While customer service, marketing strategies, and in-flight services are certainly important aspects of the airline industry, they fall more under the purview of individual airlines rather than a regulatory body like the DOT. The DOT's role is primarily regulatory and compliance-focused, ensuring consistent practices across the aviation sector that align with both national policies and international agreements.
