The story started when Texas-based Rosey Blair and her boyfriend hopped on their flight home and discovered they weren't seated together.
Fortunately another woman agreed to switch places. As she did so, Blair joked that maybe the woman's new seat partner "would be the love of her life".
But when the woman's seat mate arrived, Blair realised her off-handed comment may have been more accurate than she thought, and so she and her boyfriend started documenting the budding love story on social media.
The thread immediately went viral. It became known as the #PlaneBae saga, garnering hundreds of thousands of retweets on social media, with the story being covered by everyone from the Today show to Buzzfeed News to — yes — news.com.au.
But it's since sparked a debate over strangers' right to privacy — even if the attention being thrown at them is positive.
FROM A VIRAL LOVE STORY TO A FURIOUS BACKLASH
Euan Holden, who was later identified as the man seated in front of Blair and her partner, shared a video of himself asking people to respect the other woman's privacy.
Unfortunately, he included her name in the video, and people sought to track her down, despite the woman in question not giving permission for her identity to be shared.
In a follow-up video with her boyfriend, Blair said: "We don't have the gal's permish (permission) yet. But I'm sure you guys are sneaky." This video has since been removed.
Meanwhile, the social media conversation has moved from one pushing the virality of the "great love story" to one around consent and privacy in the internet age.
A 'VIOLATION' OF STRANGERS' PRIVACY
The #PlaneBae saga — and the subsequent backlash — sparked a series of think pieces around privacy and consent to sharing information about a stranger.
Allure's Rosemary Donahue said "boundaries apparently meant nothing to the pair", accusing Rosey of "painstakingly" creating the Twitter thread for viral gain.
"While Blair might've just gotten caught up in the story (especially since she was being egged on by followers), it highlights the importance of taking a breath and asking ourselves why we feel so entitled to others' space in public," writes Donahue.
"When these lighthearted viral threads involve unsuspecting participants, it's not a distraction. It's a violation."
Katherine Cross from The Verge said using an encounter between strangers to go viral can be "a messed-up thing to do".
"We should be thinking more seriously about the ethics of live-tweeting: when is it appropriate? When it is, what should and shouldn't you do? In Blair's case, she seemed to think that lightly obscuring the faces of the two people she surveilled was enough to be ethical.
"Yet the identities of both were inevitably pursued and eventually discovered. At a certain level of virality, you cannot stop motivated people on the internet from piercing your veils.
"In the case of that woman from Blair's flight, her legions of "fans" are digging day and night to find more information, to meet the female lead of this summer's hottest rom-com.
"They want to know what happens next. They want to make her finish the story. Go on a date; now kiss; now get engaged; tell us what it was like. We need to know more. More. More."
A number of commentators also noted the role of sexism in how the story was received — while Holden made media appearances and was praised over the stint, the unidentified woman was attacked — particularly after the pair simultaneously got up to use the bathroom.
Writing in The Atlantic, Taylor Lorenz suggests Blair's coverage denied the woman a voice in how the story turned out, serving as an example of an "obnoxious trend" to tweet about strangers.
"What sounds like romantic banter to an eavesdropper could be a nightmare for one or both of the people involved," Lorenz wrote. "Blair repeatedly implies in her thread that Helen is flirting with Holden, but was she?
"Who is to say this woman wasn't simply politely entertaining the man next to her for fear of being rude? Or perhaps she has a partner at home. She should be allowed to casually flirt or make a new friend without people on the internet suggesting that she had sex with a stranger in a plane bathroom."
HOW ROSEY ADDRESSED THE CRITICISM
After the backfire Blair tweeted an apology, saying "the last thing I want to do is to remove agency and autonomy from another woman".
She also noted that she hadn't profited off her viral fame, although she did face additional fire for attempting to wrangle a job out of Buzzfeed over it, and declaring her interest to write a screenplay.
Blair also posted a lengthy Instagram post, describing herself as "some strange variety of journalist", and saying she was hoping the story would "inspire" people to see that love is everywhere.
At the time of publishing this article, all the tweets documenting the original story are still public.
