As the spring and summer travel season takes off, Americans are once again facing one of the most important pre-flight decisions: what to wear to the airport. From sweatpants and hoodies to coordinated travel outfits, airplane attire has become its own category of fashion—and comfort doesn’t always win out.

According to a CivicScience poll of more than 15K travelers, 57% say they wear loose and comfortable clothing on a plane, while 27% opt for a standard shirt and pants. Another 13% say they wear something fashionable or formal, and 3% say something else.

Americans aged 65+ are the most likely to say they wear loose and comfortable clothing when flying, while Gen Z travelers are the least likely to do so and are more inclined to wear standard or fashionable outfits instead. Suburban residents are the most likely to favor comfort-first travel attire, while rural residents are more likely to wear standard outfits. Regionally, those living in the West are most likely to dress comfortably for flights, while Southerners are the most likely to dress up.

But demographics aren’t the only thing separating comfort flyers from style-first travelers. CivicScience data reveal notable differences in shopping habits, wardrobe preferences, and self-expression:

• Secondhand fashion: 70% of those who wear loose, comfortable outfits on planes say they own secondhand clothing, compared to 57% of those who wear non-comfy outfits.
• Cozy-day pants: When asked what pants they typically wear on a cozy day at home, comfort-first flyers are most likely to choose sweatpants (+8 points), while those who wear standard or fashionable airplane outfits are more likely to choose pajama bottoms (+8 points).
• Buying in multiple colors: Those who wear loose and comfy clothing while flying are 10 points more likely to say they buy a clothing item they love in multiple colors (26% vs. 16%).
• Wardrobe refreshes: A majority (52%) of comfort-first travelers say they rarely or never do a substantial wardrobe refresh, compared to 39% of those who wear non-comfy outfits. Instead, comfort flyers are more likely to refresh their wardrobe about once a year.
• Fashion and emotions: Those who wear standard, fashionable, or formal outfits while flying are eight points more likely to say they tend to “conceal” how they’re feeling through the way they dress.
