For what reasons will Frontier NOT refuse transportation?

Frontier Airlines, like all carriers operating under the Air Carrier Access Act (ACAA), is prohibited from refusing transportation based on certain protected categories. The ACAA specifically addresses discrimination against individuals with disabilities, ensuring they receive equal access to air travel. Simultaneously, federal laws also prohibit discrimination based on race, gender, and ethnicity in various contexts, including transportation services.

The correct response encompasses disability, gender, and race, affirming that Frontier cannot refuse service to a passenger based on any of these identities. This adherence to non-discrimination principles is essential for promoting inclusivity and equal rights in air travel. By covering disability, gender, and race, the answer illustrates a comprehensive understanding of the broad scope of protected categories under both the ACAA and civil rights laws.

While behavioral issues may influence travel eligibility, they are not covered by the non-discrimination stipulations like the other factors mentioned in the correct answer. Thus, Frontier can refuse service based on concerns related to safety or behavior, but not based on inherent characteristics that fall under legal protections.
