A mum was photographed cradling her heat-stricken baby while trapped on what she has called an unbearably hot airplane.
Now, Emily France is furious at the way the airline handled the medical crisis.
The 39-year-old mother and her four-month-old son, Owen, were flying United Airlines from Denver to El Paso, Texas, to join her husband, an astrophysicist.
Temperatures in Denver, which was experiencing a heatwave at the time, had reached 90 degrees at the Airport.
United released a statement saying: "This should have never happened and they are profoundly sorry."
Adding: "They are actively looking into what happened to prevent this from happening again."
"Medical care was provided to the child within 16 minutes of the Captain's call for paramedics."
