Travelers who are unable to walk access airplanes through a highly regulated system of assistance and specialized equipment mandated by the Air Carrier Access Act and global 2026 accessibility standards. Upon arriving at the airport, passengers can request an "airport wheelchair" and a trained assistant to navigate through security and to the gate. To board the plane, if a level-entry jet bridge is not available, airlines provide mechanical lifts or ramps to elevate the passenger to the aircraft door. Once at the aircraft, the passenger transfers from their personal wheelchair into a specialized, narrow "boarding chair" (also known as an aisle chair) designed to fit through the airplane's slim aisle. Airline personnel then assist in safely transferring the passenger into their assigned seat. In 2026, many newer aircraft are equipped with "movable armrests" on aisle seats to make this transfer more dignified and efficient. Throughout the flight, an "on-board wheelchair" is available to help the passenger reach the lavatory, ensuring that non-ambulatory travelers have full access to air travel in a safe and respectful manner.
