How to survive the flight to Crestline?
We've got the lowdown on how to make your flight as stress-free as possible. Follow our insider tips and you'll be cruising through the airport and having a ball in Crestline in no time at all.What to pack in your hand luggage:

  • Traveling on a plane can be a stress-free experience if you bring the right gear. First of all you'll need toiletry items, such as lip balm and hand cream, a fresh change of clothes and a good book. Secondly, find room in your bag for your mobile phone, a charger, any medications and perhaps a comfy neck pillow too. Lastly, don't forget to take your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray 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 trusty Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and gasoline, are also not allowed.

What to wear on a flight:

  • The key to a comfortable flight is as simple as your choice of clothes. Prepare for temperature changes by bringing layers. This will keep you nice and warm if the cabin gets too cold. Shoes like high heels and sandals are best left in your suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • The serious condition known as DVT (deep vein thrombosis) is a potential risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity. Walking around the cabin and doing regular leg and foot exercises while seated is a great way to prevent this from happening. Wearing a quality pair of compression tights or socks also helps reduce your risk.

How to get through airport security fast when flying to Crestline?
The secret is to be organized before you get to the airport security gate. That way, you'll be hopping onto that plane to Crestline in no time at all. Follow these tips and get your vacation off to a fantastic start:

  • First things first. Your boarding pass and travel ID will need to be shown to security personnel. Keep them within easy reach so you don't hold up the line.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like laptops and phones will also have to go through the machine to be scanned. Don't worry, you'll be back online in no time.
  • Traveling with your favorite hand cream? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can bring it with you in your carry-on bag.
  • There's a possibility that you'll be required to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed in the cabin.
