One person wrote, "I CANNOT APPLAUD YOU ENOUGH!!! As a medical interpreter I cannot begin to tell you how much it can appease a nervous mind/heart to have someone who speaks your language and actually can UNDERSTAND you. Your daughter made such a huge impact, and you sir made an impact as well by teaching her compassion as well as a second language! Not only is she fluent in Spanish now, she is fluent in kindness!"
"Not all sheroes wear capes!" another comment read.
People also can't stop pointing out how perfect Arrington's daughter's shirt was for the occasion.
Her shirt reads, "I got this."
Yes. Yes, you do!
These two girls give us hope for the future.
And they're a reminder that humanity is about breaking down barriers and creating connections with one another.
We're sure this is a flight that they'll never forget.
