Yes, this is a thing that can happen. When temperatures are high the air density means that planes need to achieve a higher speed to take off. Same for increased weight. Same for high altitude airports. Same when there’s less headwind to take off into.
If enough of these factors are bad enough, you have to change what you can. Can’t change the airport elevation or the weather, so that leaves you with the weight.
Proper planning prevents piss poor performance.
isnt hot air less dense than cold air ?
Yes, less air means less lift. Same issue with altitude.
It also means less air, as in density, so the fans and compressors are able to pull in less air to burn with. The fadecs compensate for this automatically but it means the output is derated till you get far enough off the ground to get speed.
i see. that makes sense now. thanks.
Ok…? Why is this news?
Agreed. This is clickbait. They want people to think that they kicked off the fat passengers.
Well that would be the logical thing to do.
Kick of the heavier passengers and they don’t have to remove as many total people. Which is overall better as you’re creating travel problems for fewer people.
Although unless you’re like 20st then it’s unlikely that it would matter a great deal whether you pick the weightier people since they’ll be making the calculation based on a formula that attributes a set value to passenger weight.
No one gets kicked off or picked. This is a quite regular occurrence in air traffic and the crew is then simply asking if someone would be willing to take a later flight. Those passengers also get some money for their inconvenience. This happens all the time.
Yeah I got $700 cash in hand and an upgrade to business class for volunteering to give up my seat on a flight from the US to Europe.

Sure, I was being hyperbolic in my language.
But they probably should, no? It would be interesting to get a combined weight of the passenger and all luggage and factor that in to the price. If a flight is relatively empty, all prices should be the same, but as it nears capacity, it should absolutely be a factor.
Unfortunately, people are very sensitive about their weight and there would be a massive uproar if any airline did it.
Good they did that. I’d probably would be one of those volunteers.
Probably better than doing it mid flight.
