Space is already at a premium on a plane, so you don't want to add anything that will make you feel even more confined. This is not the time for skintight jeans (although you may want to carry a jean jacket). “As a passenger, I always wear ponte knit pants, which offer stretch and are stylish,” says Caris.

While many people wear jeans on planes for their durability and style, travel experts and frequent flyers often recommend avoiding them, especially for long-haul flights, for several comfort and health-related reasons. First, denim is a thick, rigid fabric with very little "give" or stretch; after several hours of sitting in a cramped economy seat, the heavy seams and waistband can dig into the skin, leading to discomfort and bloating (often called "jet bloat"). Second, denim is not breathable and does not regulate temperature well; planes can swing between being freezing cold and uncomfortably hot, and once jeans get damp or sweaty, they take a long time to dry. More importantly, tight-fitting jeans can restrict blood circulation in the legs, which increases the risk of Deep Vein Thrombosis (DVT), a dangerous condition where blood clots form in the veins due to prolonged immobility. For a much better flight experience, travelers are encouraged to wear "technical" travel pants, leggings, or loose-fitting joggers made from breathable, moisture-wicking materials. These fabrics allow for better movement, help regulate body temperature, and reduce the physical pressure on the legs and abdomen, making it much easier to rest or sleep during a long journey.
