How to survive the flight to Thornton?
If you’re not prepared, airports and flying can be a real challenge. But don’t hit the panic button just yet. Follow these tips and tricks for a hassle-free start to your time in Thornton.What to pack in your hand luggage:

  • First of all, pack in your passport, travel docs, wallet and vital medications. Next, you’ll want some entertainment to while away the hours. A juicy novel and a phone filled with your favourite movies are good options. If you hope to catch up on some sleep, a comfy neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a few toiletry items to ensure you step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have a sharp object hiding in one of the compartments of your carry-on luggage. Other restricted items include explosive or flammable substances, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The answer to a comfortable flight often lies in your choice of clothes. Prepare for temperature changes by layering up. This will keep you nice and warm if the cabin gets too cold. Shoes like sandals and heels are best left in your checked suitcase. Instead, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you for it.
  • Unfortunately, a risk of flying long-haul is developing deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity. To avoid this, make the most of every opportunity to stretch your legs and walk around the cabin. Compression socks and tights are another simple way to help reduce this risk.

How to get through airport security fast when flying to Thornton?
Being prepared before you get to the airport will help make your trip to Thornton a pleasure. Below are some handy tips for a speedy journey through security:

  • Security personnel first need to know that you have a valid passport and matching travel documents before anything else. Have them ready for inspection.
  • Time to strip down. Well kind of. Your coat, belt, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • All your electronic gadgets, including your phone and tablet, will also need to be separately scanned.
  • Want to bring along your favourite hand cream? 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, you’re allowed to bring it with you in your carry-on luggage.
  • The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren’t.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won’t be allowed on board.
