8 things to know before you fly this weekend

If your holiday weekend plans include air travel, there are some moves you can make to avoid getting caught in gridlock making your way through security and on to your destination:

▪ Security lines are longer than usual. Allow extra time — two hours for a domestic flight, and three for international, according to the Transportation Security Administration.

▪ At Miami International Airport, Concourse D#2 is now exclusively dedicated to passengers using TSA Pre✓; passengers flying from concourses H or J can use the TSA Pre✓ lane at Concourse H. Passengers using CLEAR will find dedicated lanes at concourses E and H.

▪ U.S. passport holders can avoid lines by downloading and using the free mobile passport app at mobilepassport.us.

▪ Miami International Airport’s app has been updated and now includes flight schedules and local weather forecasts plus shopping and dining options. Download it in the Apple App Store or Google Play.

▪ Fort Lauderdale-Hollywood International Airport’s bilingual app includes flight status, gate information and airport maps. Download it for free at the Apple App Store or Google Play.

▪ Download your airline’s app onto your smart phone before you go, so you can respond quickly if your flight is delayed. (Several thunderstorms are forecast Friday in the Midwest.)

▪ The 3-1-1 rule still applies to liquids and gels. That means no more than 3.4 ounces per container, placed in a single, clear, one-quart plastic bag in carry-on.

▪ Children 12 and under aren’t required to remove their shoes.
