I have to say that reasonable accommodations become, the majority of the time, unreasonable accommodations. Often, instead of being useful to us, these accommodations even complicate our lives.
Also, how can we rely on airlines and their goodwill when they ask manufacturers to install as many seats as possible on the plane in order to have as many people on board as possible? We ask them to make space for disabled people, but for these companies, I think it's a question of money. They completely forget that we should have the same rights as all other passengers. We have the right to exist and to be there.
I think the airlines should be forced to change their ways. They should now be obliged to provide spaces for people with disabilities, adapt their bathrooms and make any other accommodations, just as all other carriers do, whether by land or otherwise.
