Opt for a pair of slip-on shoes, dress in loose, breathable clothing and remember to bring a sweater in case you get chilly in the cabin. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Boulder? > - Security personnel first need to see that you have a valid passport and travel documents before anything else. Have them ready to show. > - The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets.
