If you're curious about what it's like for me when I travel and what accessibility is like at an international airport, here's my POV from a recent trip.
I should mention accessibility at airports is far from perfect. I've been lucky and haven't had a lot of issues personally. But for my friends and other folks, I've seen, there are a lot of issues that come up constantly. Airport attendants are often not fully trained in handling people with disabilities. Especially for folks with wheelchairs. They also think EVERY disability needs a wheelchair. Also, often, you can be ignored, forgotten, or mistreated. I hope airport accessibility is improved everywhere so you can get a consistent experience soon.
