Tips for keeping the TSA lines moving

• Bringing gifts? Don’t wrap them. They may need to be inspected. • Know what’s OK to put in carry-on and checked bags. Get information at tsatraveltips.us/can-i-bring-it-on-an-airplane. Still not clear? Travelers also can tweet photos of items they want to bring on a plane to @AskTSA and get advice in about 20 minutes. • Knives and firearms can’t be carried on, and yet, Denver International Airport records some of the highest numbers of gun seizures at its TSA checkpoints. Though the end of November, screeners had discovered more 90 firearms. Security lines come to a halt when a gun is found. • Clean out your bag. The clutter can slow screening.
