The European Commission, Directorate-General for Energy and Transport, presents "Air transport: New rights for people with reduced mobility". People with disabilities or reduced mobility and the elderly: nearly one European in five may need special assistance for travelling or communicating.
European regulations lay down measures applicable at every EU airport to guarantee that you habe equal access to air transport without discrimination and at no additional cost. No one can refuse your booking or your right to board because of your disability or mobility problem. The only exeptions concern potential safety issues justified by a national or international regulation or technical impossibility, such as the limited size of the aircraft.
