Do you have any tips for my flight to Barnhart?
If you're not prepared, travelling can be overwhelming. But don't hit the panic button just yet. Follow these useful tips for a trouble-free start to your time in Barnhart. What to pack in your hand luggage:

  • The trick to having a worry-free travel experience is to plan ahead. So, let's start with the essentials: passport, official ID, credit cards and medications. Next, bring on board items that'll help keep you occupied, like some electronic devices or a good read. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, don't forget to squeeze in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and matches, are also banned.

What to wear on a flight:

  • Your main priority is to feel as comfortable as possible. Pick a pair of flat, closed-toe shoes, dress in loose, natural fibers and remember to take a jacket in case it gets cold in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression socks or tights and keep your feet and legs moving.

How to get through airport security fast when flying to Barnhart?
The secret is to be prepared before you arrive at security. That way, you'll be hopping onto that plane to Barnhart in a flash. Follow these tips and get your vacation off to a fantastic start:

  • Be sure to have your passport and travel documents at hand. They're the first things you'll be asked to show at airport security.
  • Your belt, coat, keys and other items in your pocket, like your headphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronic devices will also need to be sent through the scanner.
  • Don't forget to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
