Do you have any tips for my flight to Tonica?
If you're not prepared, air travel can be testing. But don't hit the panic button just yet. Follow these handy hints and enjoy a stress-free start to your vacation in Tonica. What to pack in your hand luggage:

  • A plane trip can be a cruisy experience if you pack the right stuff. First things first, you'll need basic toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and something to read. Next, find room in your carry-on bag for your electronic devices, chargers, medications and perhaps a comfy neck pillow as well. Last, but definitely not least, remember to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your precious pocket knife, and dangerous products which are flammable or explosive, such as aerosols and poisons, are also restricted.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer your clothing and opt for shoes that are enclosed, flat and easy to pull on and off.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long flights. Reduce the risks by drinking water, keeping your legs and feet moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Tonica?
The simple answer is — be prepared. We've put together some top tips for an easy trip through airport security. Watch out Tonica, here you come:

  • Your passport and travel documents will need to be shown to security personnel. Keep them at hand so you don't hold up the queue.
  • Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items such as your belt, jacket and headphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronic gadgets will also need to be sent through the scanner.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and other heavy-style shoes are usually subjected to additional screening.
  • Knives and other sharp items can't be taken on board. They'll be confiscated at security, so put them in your checked luggage.
