Wherever you're coming from, flying can be a seamless experience if you're well organized. Take a peek at these handy tips and tricks that will get your La Forteresse escape started on the right foot.What to pack in your hand luggage:

  • First things first, put in your passport, important documents, bank cards and medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling novel and a laptop crammed with your favorite shows are some great options. If you intend to catch up on some sleep, a neck pillow and some earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant to ensure you arrive feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your pocket knife, and products which are explosive or flammable, such as aerosol cans, spray paint and gasoline, are also prohibited.

What to wear on a flight:

  • Comfort should always be the goal when choosing what to wear during your flight. Consider your footwear carefully too, as swollen ankles and feet are quite common. Roomy, closed-toed shoes work well.
  • Most travelers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. There are plenty of ways to lessen your risk. Wear compression tights or socks, stay well hydrated and remember to keep your legs and feet moving. Walk around the cabin when possible or perform some simple exercises in your seat.

How to get through airport security fast when flying to La Forteresse?
The answer is — be prepared. We've compiled some top tips for a speedy trip through airport security. Look out La Forteresse, here you come:

  • Airport security personnel first need to make sure that you have a valid ID and travel documents before anything else. Have them ready for inspection.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
  • Want to bring along your favorite perfume or cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's OK to bring with you in your carry-on.
  • There's a good chance you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a good idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed in the cabin.
