According to Wikipedia Greta did not fly back from her trip to the Americas:
"Thunberg refuses to fly because of the carbon emissions from air travel so she posted on social media that she needed a ride across the Atlantic Ocean. Riley Whitelum and Elayna Carausu, an Australian couple who had been sailing around the world aboard their 48-foot (15 m) catamaran, La Vagabonde, offered to take her, assisted by professional yacht skipper Nikki Henderson. So, on 13 November 2019, Thunberg and her father set sail from Hampton, Virginia for Lisbon, Portugal." [https://en.wikipedia.org/wiki/Voyage_of_Greta_Thunberg]
PS There was some talk that a crew had to fly out to bring the boat back.
