According to an IMDB page for “Covid Flight”
posted by the Twitter account @HoaxEye, the role of the irate Karen was played by
Diana Winter, an English actor from Bournemouth, United Kingdom who is registered with UK Equity and has appeared in a smattering of short films. The role of the flight attendant appears to have been played by an actor named Jordan Holland, who is represented by the agency Aston Management and wrote a now-deleted post on her Facebook about her experience working on the film. “Great fun filming today with a fun crew! Got to play the part of an airline hostess dealing with a not-so-happy Karen,” she wrote in the caption of the post, which featured a photo of the cast and crew, including Winter, on the airplane seen in the viral video. (Holland and Aston Management did not immediately respond to requests for comment, nor did Williams.)
The director credited on IMDB as helming the video, Jamie Hull-Greenwood, also posted
photos from the set on Instagram, including a selfie also dated Oct. 27 of the airplane interior that shows Holland in her flight attendant costume in the frame. “Filming on a plane for Prince Ea, directing a micro short is normally fun but with a fear of flying it’s pretty scary,” he wrote in the caption of a
selfie showing him in the cockpit, followed by the “joy” emoji.
