What's Missing from Airline Access

The Air Carrier Access Act (ACAA) has just been updated. Considering the issues with airline access for people on the spectrum, perhaps the updates would include some improvements for us.

The ACAA starts off strong for us as it states explicitly (emphasis mine),

The ACAA protects individuals who have a disability. Under the ACAA, an individual with a disability is a person who has a physical or mental impairment that, on a permanent or temporary basis, substantially limits one or more major life activities, has a record of such an impairment, or is regarded as having such an impairment.

However, while a number of specific protections, accommodations, and clarifications exist for the accommodations required of the airlines to serve people with mobility or sensory disabilities, the only mention of mental disabilities made in the rest of the thing seems to be regarding when an assistant is required ("a passenger who, because of mental disabilities, is unable to comprehend or respond appropriately to safety instructions from carrier personnel;"). There is nothing that gives any sort of guidance to airlines about what sort of accommodations or support are necessary for including people with mental-related or social-related disabilities in air travel.

This is the same issue with the accessible meetings document. I'm thrilled to see better and better consideration of disability accommodations and implementation of anti-discrimination law, but people with social, learning, or intellectual disabilities continue to be left out of the discussion.

How can we get our needs better included in the creation of anti-discrimination policy, the implementation of anti-discrimination policy, and the provisioning of documentation and training to the public service sector?
