She thought she could fly under the radar.

A viral TikTok captured a shocking moment when a woman was caught vaping on a plane—right in front of a flight attendant. The clip shows her casually taking a puff before being told, “Ma’am, you can’t do that.” Though she apologized and hid the e-cigarette, her attitude quickly turned dismissive.

The video exploded online, racking up over 64 million views. Viewers were stunned by her audacity, while some found humor in the silent, unfazed passenger seated beside her.

In a follow-up clip, airline staff removed the woman from the flight. Vaping on planes is a federal offense and can lead to fines of up to $1,771.

Moral of the story? Don’t vape and fly—airline rules are no joke.
