Do you have any tips for my flight to Caspar?
No matter where you're coming from, flying can be a pleasant experience if you prepare well enough. We've compiled a list of top travel tips that will help get your Caspar escape started on the right note. What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to be prepared. So, let's start with the basics: passport, official ID, credit cards and medications. Next, bring on board items that'll help while away those hours, like some electronic gadgets or a good read. You'll also want to bring your chargers, a quality neck pillow and a pair of earplugs. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp or pointed objects, like your treasured Swiss Army knife, and products which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also prohibited.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes by donning layers, and pick slightly roomy, flat shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Caspar?
It's all about being prepared. We've rounded up some handy tips and tricks for a fuss-free trip through airport security. Look out Caspar, here you come:

  • Your ID and travel documents will need to be presented to airport security personnel. Keep them within easy reach so you don't hold up the queue.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online in no time.
  • Traveling with a new hand and nail cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're permitted to bring it with you in your carry-on bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Take all prohibited items out of 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 in the cabin.
