Her post resonated with more than 6,000 people on the social media site.
In fact, he wasn't.
Hage said she was "shaking right now" as the terrible incident unfolded. "I am crumpled into a ball trying to not bother. i'm just so upset".
"LOUDLY huffing, sighing, and readjusting himself in his seat". So she confronted him about it, just to let him know that if he didn't have anything nice to text perhaps he could just put his phone into airplane mode and enjoy the view from the window.
The next time the man texted, Hage snuck a look and discovered that the texts were about her. Hage says the texts were "mean and ugly" and she feels "positive" he took photos of her.
He received a text saying, "Hopefully she didn't have any Mexican food", and his response back was "I think she ate a Mexican".
Hage noticed he started texting about her and even took photos so she looked to see what he said.
In the video, Hage points out that the man was texting about her, to which he denies, before the model recounts some of the text she saw.
"I didn't do anything to him. You can be completely in your own space, not bothering anyone and people will still fuck with you and try to hurt you", Hage said.
Hage goes on to say incidents like these are "a fat person's daily reality", before finishing the post with the line: "This just makes me a mixture of enraged and super sad".
Natalie Hage was headed to Los Angeles on an American Airlines flight when the man next to her began making it obvious that he wasn't thrilled by her presence next to him.
But then, the man -supposedly under the influence of alcohol - chastises her size even further attempting to explain why she shouldn't sit in the exit seat.
"I'm sorry, I was drinking", he said. Ruining any genuine apology, however, he later asked the model whether she'd be capable of helping people get off the plane in an emergency. Wow. She recorded the exchange in which she was heard telling him: "Do you normally make fun of fat people?"
Hage said she "purposely did not film his face", so as not to shame him individually when she recorded the now-viral video, but Hage said "he was embarrassed that he got caught".
