In my opinion, the perception that wearing jeans on a plane is a mistake is false. I travel a lot, and I can count the number of times I've worn leggings or sweatpants for a flight on one hand (and most of those were international flights). What is a mistake—and it's one that I've regrettably made—is wearing stiff, 100% cotton jeans on planes. Even if it's a quick flight, sitting straight up in an uncomfortable plane seat while wearing uncomfortable jeans can't be good for your organs or your mental state. But the good news is that there are plenty of comfortable, stretchy jeans on the market that are also very stylish.
I can say from personal experience that a pair of jeans with a significant amount of stretch is comfortable and flexible enough to wear on a long cross-country flight or even an international one. And since the summer travel season is upon us, I scoured the internet and found the 24 best airplane jeans on the market.
