Marisa Fotieo, a teacher from Michigan, said she began to have a painful throat halfway through the trip, so she decided to take a rapid test on the plane, she told NBC news.
“I just took my rapid test and I brought it into the bathroom, and within what felt like two seconds there were two lines,” she said in the interview, which indicates a positive test.
Fotieo had received two negative PCR tests prior to the flight, and is now self-isolating in Iceland.
She posted a video from the loo on TikTok, which has been viewed more than 4 million times since it was uploaded on 21 December.
She was provided with food and drinks by a flight attendant for the remainder of the flight.
“Shout out to Icelandair for my VIP quarantine quarters,” she added.
