In 1999, Aer Rianta introduced a by-law which requires service providers at the State airports to make available such facilities as are necessary for passengers with disabilities in order that they may avail of all airport services. This by-law, together with the more recent special protocol to which I referred earlier, has assisted in making people in general and, in particular, people with disabilities, more aware of their rights and has heightened awareness of the issue of facilitating people with disabilities at the airports.
