I am flying to Chicago on February 28th. Should I wear jeans to the airport? Any advice for airport security and packing?
Jeans are fine - dress comfortably, for sure. If you want advice about packing and security, then I'd suggest asking more specific questions. There is a lot of information that can be provided, but that's a pretty vague and broad question. You should be sure to look at the TSA and airline regulations regarding your carry-on bags and what can go in them (pay attention to the liquid/gel rule). Metal is generally not an issue at security anymore. Most all airports - even small ones - are now using body scanners instead of metal detectors. They don't react to metal. Even metal detectors generally do not react to normal amounts of jewelry and metal on clothing. Wear shoes that are easy to remove and put back on, because you'll have to take them off at security. Again, ask more specific questions and the people here will be happy to give you more information.
If you are comfortable with wearing jeans, go for it. You may want to bring a pair of sweatpants or something to change as it could get a little uncomfortable if you sit for a long period of time. You also may need to layer up once you get to chicago.
Jeans are fine. A lot of people wear them when they fly
Comfort and weather at destination are the 2 biggest concerns One December many years ago I departed the tropics, dressed in light weight trousers, short sleeve shirt and sandals, forgetting that when I arrived in Detroit it would be below freezing
You can wear jeans to the Airport if you want to. Suggest you where something that is comfortable to sit in for a few hours. May want to check the weather forecast and pack any additional clothing that is appropriate for the expected weather. Gloves, a warm jacket, maybe something for your feet.A hat a scarf or whatever in addition to just some pants. Any advice for airport security and packing? Do as instructed and expect a wait. Pack as light as possible you have to haul all of it around with you getting to and from the Airports. https://www.tsa.gov/travel/security-screening/whatcanibring/all STORMS happen to disrupt travel. Not a bad idea to show up early.
Yes. Wear something comfortable and warm. I don't know your starting point, but Chicago is -17 right now. So if jeans are your definition of warm and comfortable wear them. I'd wear a pair without rivets though. Too much metal isn't security friendly. Also no jewelry is security friendly.
