Airline passengers know to expect possible flight delays when weather forecasts call for thunderstorms, heavy snow or strong wind. The omens are less obvious on a hot summer day with clear skies.
Yet extreme heat also disrupts flights and travel plans. On the hottest days, thinner air can make it harder for aircraft to get off the ground safely. Airlines may have to lighten the load by removing passengers or cargo, or carrying less fuel.
The snag is well known at airports in desert climates around the world, from the U.S. Southwest to the Middle East. But even less extreme heat can create similar challenges at airports with higher elevations or shorter runways. Researchers say human-caused climate change could make such disruptions more common.
With heat waves searing parts of the United States and Europe this summer, Las Vegas illustrated how extreme heat can interfere with air travel. American Airlines offered compensation to customers who voluntarily gave up their seats on a July 24 flight from Harry Reid International Airport after temperatures reached 114 degrees Fahrenheit (47 degrees Celsius).
The airline described reducing a plane’s weight as a standard industry practice in hot-weather destinations when conditions require it to ensure a safe takeoff. The explanation comes down to physics.
Hot air is thinner than cool air, making it harder for a plane’s wings to generate lift and for jet engines to generate the thrust needed for takeoff, explained Ross Aimer, a retired United Airlines captain and CEO of Aero Consulting Experts.
“There is a science behind all this,” Aimer said. “You can’t deny the science of flight and what it takes for an airplane to operate.”

You can easily see the difference when taking off in a Cessna 172 one day with normal temps and humidity and another day when it is over 100 and high humidity. Take-off roll is a lot longer.
I’m in Texas and we’re in the heat doldrums months now, where we hit 100 almost every day.
It’s actually been cool this year in that the temps only go slightly above 100. We’ve had years in the past where we’d go to 108 for highs weeks on end.
And this concludes your daily installment of AP fear porn.

We don’t hate the media enough
Or not. But I pity the poor baggage handlers.
Oh! This is so new! Global warming is so terrible.
The first time this happened to me on a flight was August, 1971. It never happened on airline flights in the 1800s. We are all going to die, i guess.
In before the “I don’t fly” post.
But I thought the environmental warriors wanted people to fly less. So why isn’t this good news.
Does this mean more winter flights will be on time?
Lol.
This occasionally happens in AZ.
Mostly landings.
I don’t fly...
If it’s man made global warming does it mean Al Gore will donate his private jet for people to use now? Giant carbon footprint but people need to go places.
Also, how do you explain the growth in 737 engine size (higher bypass efficiency and passenger obesity are just conspiracy theories)?
I don’t fly. Just too damn old.
True that!
our local airport shoots the planes over the bay when it is hot. the noise is tremendous. I imaging the water is cool.
Heavy snow has always been caused by elevated temperatures. < /sarc>
“Yet extreme heat…”
Utter crap. Temps aren’t anywhere near the no-go range.
Bring back water injection !!
AP is the worst of the climate BS’ers. You can always count on them for the worst of the lies. They will never give up the con.
