There's a service now being offered by American Express in the United States for its members who are travelling with disabilities. American Express will actually provide an individual to meet you at the airport and follow you along your journey until you get onto the plane, and then there will be another representative on the other side, if that's the service in the States.
If you want one thing, I reiterate what Maayan Ziv said. If we are going to start collecting data and start providing the in-person service to help make sure we don't have to relitigate all the time, then there's one person whom it's helping—me and the people with me—to get to where they need to go.
