One young girl on a United Airlines flight received an unexpected note after she lost her tooth aboard a plane.

6-year-old, Lena Larmon, from Lexington, South Carolina loves to travel with her family. She’s been to 35 countries and even celebrated her second birthday party at the Columbia Metropolitan Airport.

Lena and her family were on a 36-hour delay in New York while trying to return home from a trip to Norway.

Upon landing, they left the plane without something, and that something was little Lena’s bottom tooth.

“I was sleeping on the airplane. My mom woke me up … and we were going to go pick our suitcases up. And I said, ‘Mommy, mommy, I think my tooth fell out,'” Lena told Good Morning America.

“We tried to walk back to the airplane, but security was closed. It was 2 a.m..”

She never expected her tooth to fall out on the flight, which resulted in a “very emotional” and teary-eyed realization.

With nothing to leave for the tooth fairy, “Captain Josh”, (as Lena called him), who piloted her flight was there to save the day, offering to write up a letter to the tooth fairy.

“Dear tooth fairy, Lena had a tooth fall out on her flight to Greenville,” Captain Josh Duchow wrote. “Please take this note in place of her tooth.”

The airline gained traction for this heartwarming gesture, and a United spokesperson was glad to see moments like that as they are committed to going above and beyond for the community.

As for Lena, the tooth fairy even wrote back to her.

“She said, ‘Lena, it is OK that you have lost your tooth on the airplane. I will get it. Keep brushing,” Lena recalled.

Both Lena and her family were grateful for the kind Captain and his note that traveled all the way to the tooth fairy.

“Thank you to Captain Josh for stepping in and helping me. You were very nice to me and thank you for being nice to me,” Lena said with a smile.
