Do you have any tips for my flight to Clearlake?
Wherever you're jetting in from, flying can be a pleasant experience if you've prepared well. Follow these handy tips that will get your Clearlake vacation started on the right foot. What to pack in your hand luggage:

  • It's simple — first, put in your passport, travel docs, bank cards and daily medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling novel and a tablet filled with your favourite shows are some wonderful options. If you intend to catch a few z's, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, make room for a few toiletry items so you'll touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like a pocket knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and matches, are also prohibited.

What to wear on a flight:

  • Comfort should be your highest priority when choosing what to wear during your flight. Loose clothing is a sensible choice, as are enclosed shoes like sneakers.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Clearlake?
The trick is to be organized before you arrive at airport security. That way, you'll be boarding that plane to Clearlake in a flash. Follow these helpful tips and get your vacation off to a flying start:

  • Have your passport and travel documents within easy reach. They'll be the first things you'll be asked to show at security.
  • After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry though, you'll be back online before you know it.
  • Don't forget to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight 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 on board and will be confiscated.
