What is "deltalina"

Katherine Lee, better known as Deltalina, is a former flight attendant for Delta Air Lines and from 2008 with cameo appearances starting in 2012 to 2015 was one of the presenters of Delta's onboard safety videos. The first Deltalina safety video was released in February 2008 and quickly became popular not only on board but also became one of the most-watched videos on YouTube soon after its release. Martin Grant of Forbes wrote in 2012 that the Deltalina video was the first of the "next generation of safety video" and that the "talents" of Deltalina "largely helped" this. Ian Bogost, author of How to Do Things With Videogames, wrote that the video made her into "a minor celebrity".
