Do you have any tips for my flight to Caldwell?
Depending on where you're coming from, your trip to Caldwell could be a breeze or it could drag on forever. Below are some handy hints that will help you start your next great escape on the right foot. What to pack in your hand luggage:

  • A plane ride can be a cruisy experience if you take the right gear. First of all you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a spare change of clothes and something to read. Next, leave space in your hand luggage for your electronic gadgets, chargers, your important medications and maybe a comfy neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes things like screwdrivers, drills, aerosol cans and bleaching agents. Sporting equipment like ski poles, and items that could injure passengers, such as pepper spray and guns, aren't allowed in the cabin either.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick slightly roomy, flat shoes like sneakers.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Caldwell?
As seasoned travellers know, the secret is to be prepared before you arrive at security. That way, you'll be stepping onto that plane to Caldwell before you know it. Follow these tips and get your trip off to a fantastic start:

  • Security personnel first need to determine that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them ready to show.
  • Time to strip down. Well kind of. Your belt, coat, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
  • All electronic devices, including your phone and tablet, will also need to be scanned.
  • Can't travel without your favourite cologne or perfume? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on.
  • The right choice of footwear can save you several precious minutes. Boots and heavy 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 the cabin. If you need to bring these kinds of items, check them in.
