A teenage girl who comforted a disabled passenger on a flight has been praised as an "angel".
Clara Daly, 15, came to the aid of deaf and blind passenger Tim Cook on an Alaska Airlines flight from Boston to Portland.
Crew efforts to communicate with and comfort Mr Cook were unsuccessful, so they put the call out to see if any passengers knew sign language - and along came Clara.
Mr Cook told Portland TV station KGW8 she was "an angel", sitting with and aiding him for nearly six hours as other passengers watched in awe. Mr Cook felt her hands as she signed.
Clara told cabin crew she learnt sign language to help with her own dyslexia.
Passenger Lynette Scribner posted a picture of the pair on Facebook.
"I can't say enough about this beautiful young woman named Clara who didn't think twice about helping her fellow passenger," Ms Scribner's post read.
"It was a beautiful reminder, in this time of too much awfulness, that there are still good, good people who are willing to look out for each other."
