Leigh-Allyn Baker posted a video of herself soaking her feet in a cup of ice water after her flight sat on the runway for about two hours with almost no air conditioning.
Baker said the stunt was a practical way to cool down during menopause symptoms, adding that she chose humor over complaining and that nearby passengers were laughing along.
Online reaction split quickly: some viewers called the move creative and relatable, while others said using a drinking cup for a foot soak on a plane was unsanitary.
In comments, Baker said her feet never touched the airplane floor, but etiquette expert Diane Gottsman said passengers in confined spaces should avoid behavior likely to bother others.
