Biles shared a clip about the incident on Instagram stories with copy that read: "not the flight attendant trying to give me a coloring book when I board…"
At four feet 2 inches (1.42 cm), Biles isn't exactly tall, but mistaking the world-record smashing athlete for a child is a stretch.
The copy continued:"I said 'no I'm good, I'm 25.'"
The crew reportedly redeemed themselves by offering her a drink and Biles shared a clip holding a full glass with the caption: "the other flight attendant gave me a mimosa so we're in the clear."
However, Biles was still asked if she was old enough to drink when it was brought over.
One fan couldn't cope with the idea, and took to Twitter, sharing a screenshot of the story.
YouTuber Matt Bernstein saw the funny side of Biles' predicament.
"i'm crying at the thought of a flight attendant giving simone biles the most decorated gymnast in history a coloring book because she is 4'8," they wrote.
Simone Biles' size may be a drawback while travelling but it's a huge advantage when she's competing against other athletes.
In general, world-class gymnasts tend to be on the shorter side, as not only are they lighter (which provides a higher strength-to-weight ratio), and also help with rotational skills for tricks like somersaults.
