What levels and types of wheelchair assistance are available at the airport and on the airplane? What are SSR codes?

Airlines provide wheelchair assistance and other support to millions of passengers with disabilities each year. When a traveler requests special assistance, the airline codes that into their ticket record using a special service request code, or SSR. These codes allow airlines to easily keep track of assistance requests and assign staff accordingly.

It is important that the correct code(s) be placed in your record to ensure that the assistance provided is appropriate and timely. The tables below identify and define the types of assistance and SSR codes of interest to air travelers with disabilities.
