Airline travel today is nothing like what it was ten years ago, and new rules and regulations are constantly going into effect. On a hectic day of travel, the last thing anyone wants is to be held up at a security checkpoint because of some new policy you weren’t aware of. To help you avoid the hassle o such a situation, we’re offering you a little advice to help navigate some of the most recent changes.The 3-1-1 rule regarding carry-on liquids has been in effect for some time now, yet it still is one of the most common causes of delay in the security line. This regulation requires that liquids in your carry on must all be contained within one, one-quart size zip top bag, and each liquid within the bag must be carried in a 3-ounce container or smaller. Many people forget this applies to things such as toothpaste, lip gloss, and hand lotion. If you can’t fit all of your liquids into these size containers, you may have to either return to the airline desk and check them or throw them away. Most drug stores carry travel-size toiletries to help facilitate this regulation. Pack all of your liquids accordingly, so you aren’t scrambling at the last minute to make them fit.One of the most frustrating recent changes in airline luggage policy is the change in baggage fees. While most airlines used to allow two checked bag at no charge, most airlines now charge you for even your first bag on a domestic flight. Stricter regulations on the weight limit usually result in overage fees if your bag weighs more than 50 lbs. Before you leave for the airport, weigh your luggage on a home scale, so you won’t be caught off guard at the airport. It’s also a good idea to leave a few pounds worth of room for souvenirs.These are just a few things to prepare for when you’re traveling, and you should always check with your airline before your departure.
