"Deltalina" is the nickname given to Katherine Lee, flight attendant for Delta Air Lines and since 2008-2012, 2015-, main presenter 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.
With her high cheekbones, and broad, welcoming smile, Lee was soon compared to Angelina Jolie and the nickname Deltalina (from "Delta" + "-lina") appeared on blogs and YouTube comments.
through unexpected elements in the video's "plot"
through humor — including Lee's famous finger-wag when warning passengers that "smoking is not allowed" and a computerized sparkle on the teeth of flight attendant Perry de Vlugt when he demonstrates the proper use of a life vest
The videos were criticized in the book How to Do Things With Videogames by Ian Bogost because, in Bogost's opinion, the attention that is paid to the videos is given to Lee and not to the actual safety instructions.
In 2012 Delta produced two new safety videos in which Lee is not the presenter, but in which she does appear in a cameo role, admonishing against smoking on board with her famous finger wag.
Prior to her fame as "Deltalina," Lee appeared giving live safety briefing in the May 22, 2007 episode of The Ellen DeGeneres Show when the entire show took place aboard a Delta flight.
In September 2008 Lee shot a series of humorous instructional videos for the Atlanta Falcons football team, shown on the large screens at the Georgia Dome in advance of each home game. The videos' theme was "Delta Safety First".
In March 2009, Lee helped celebrate the opening of the heliport atop the W HotelDowntown Atlanta, accompanying developer Hal Barry and his wife in a helicopter which landed there, kicking off the party. Tycoon Barry, inspiration for the protagonist in the Tom Wolfe novel A Man in Full, intended to commute between downtown and his estate 50 miles (80 km) further south. In the same month Lee appeared both in print and video to help kick off the relaunch of Delta's inflight magazine, Sky.
In 2011 (November 2010), Lee served as spokesperson in an infomercial for Healthy Trim, a diet supplement. In January 2012 (October 21,2011) , Lee appeared on CNN offering travel tips. In the November 2012 Lee appeared in a print ad for the Atlanta Convention and Visitors Bureau, which appeared in Delta Sky Magazine.
