While some airlines have mandatory training on how to assist people with disabilities, the advances in technology have made it easier for people with disabilities to travel. Apps like Be My Eyes and Aira can help people with visual disabilities navigate through airports independently. Wheelchair ramps and lifts allow people with mobility disabilities to board buses and trains.  Transportation systems could still use some improvements.

They are governed by the Air Carrier Access Act. This does not have as many accessibility standards as the ADA. For example, people who use wheelchairs must leave them at the entrance to the plane, transfer to the airline's wheelchair and then to a seat on the plane. Travel on buses and trains can be challenging as some drivers do not know how to operate the lifts and some ramps have a steep incline, which is dangerous and violates the ADA.
