Jackets and Coats It's OK to wear a coat to the airport, of course, but it helps the security line move faster if you remember to take it off and put it in a screening bin before proceeding through the metal detector or body scanner (AIT).

Yes, you should almost always bring a light, packable jacket to the airport, even if you are traveling between two tropical destinations. Airport terminals and airplane cabins are notorious for their aggressive air conditioning, often kept at temperatures between 18°C and 21°C (64°F–70°F) to keep passengers alert and reduce the risk of fainting in crowded spaces. Furthermore, having a jacket with pockets is a "travel hack" for 2026; it allows you to store your phone, passport, and power bank during security checks, so you can simply place the jacket in the bin rather than emptying individual pockets. A jacket also serves as a makeshift pillow or blanket during long layovers or red-eye flights. If you're worried about heat upon arrival, choose a moisture-wicking "tech" hoodie or a light windbreaker that can be easily clipped to the outside of your carry-on bag once you exit the airport.
