Yesterday on BBC Radio 5 there was significant discussion about this scheme. The scheme started at Heathrow Airport Passengers with Additional Needs/Hidden Disabilities can wear this lanyard or pin to make the staff aware of their hidden disabilities, allowing their teams to tailor their approach. You may use the lanyards or pins whether or not you have requested assistance.
This is now more widespread and available at most UK airports, with Sainsbury’s and Tesco supermarkets trailing the scheme in some of their stores. You can request the lanyards at most UK airports. For example you can email Edinburgh Airport and they will send it out to you, not sure if this is available at other airports.
This is a great scheme that needs more publicity and is great to help our children in these challenging environments.
