Passengers aboard a Las Vegas Delta Air Lines flight passed out and required medical treatment as temperatures outside soared past 100 degrees

• Delta passengers aboard an Atlanta-bound flight never made it out of the Las Vegas airport Monday.
• They sat on the plane for hours in high heat; a journalist aboard said there wasn't air conditioning.

Passengers on an Atlanta-bound Delta Air Lines flight from Harry Reid International Airport in Las Vegas appeared to develop heat stroke Monday after temperatures soared well above 100 degrees Fahrenheit.

The passengers are among the victims of a string of record heat waves across the US and the world. According to Fox Business, citing a Fox News field producer who was on the plane, the Delta flight was taxiing behind several planes while temperatures on board became unbearable.

The field producer, Krista Garvin, said that passengers were on the plane for close to four hours and that paramedics were called because some passengers had lost consciousness and others had soiled themselves.

Garvin told Fox Business that passengers had been given the option to leave because the plane was waiting for a clear runway but that they were told they could have to wait days for a new flight to Atlanta.

Everyone on the plane eventually disembarked after the situation worsened, with Fox Business saying the pilot told passengers experiencing medical issues to press their call button.

Temperatures near the airport on Monday got only about as low as 89 F early in the morning, according to the National Weather Service, before rising as high as 116 F, or about 46 Celsius, in the afternoon, when the flight was scheduled to take off.

A Delta representative told Insider that the passengers had been compensated and that others were helped with new flights. The airline also confirmed that first responders had treated at least one passenger because of the heat.

"We apologize for the experience our customers had on flight 555 from Las Vegas to Atlanta on July 17, which ultimately resulted in a flight cancelation," Delta said in the statement. "Delta teams are looking into the circumstances that led to uncomfortable temperatures inside the cabin and we appreciate the efforts of our people and first responders at Harry Reid International."

Correction: July 19, 2023 — An earlier version of this story misstated which day the heat-related incident aboard the Delta flight took place. It was Monday, not Tuesday.
