Do you have any tips for my flight to Portola Valley?
Depending on where you're coming from, your trip to Portola Valley could be no sweat at all or it could drag on forever. Here are some useful tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • Traveling on a plane can be a pleasure if you carry the right stuff. Firstly, you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a clean pair of socks and a good novel. Secondly, find room in your carry-on bag for your phone and charger, any medications and maybe a proper neck pillow too. Lastly, remember to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a pocket knife hiding in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive substances, like aerosols and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in temperature by dressing in layers, and pick flat, slightly roomy shoes like slip-ons.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Portola Valley?
The answer is simple — be prepared. We've put together some tips and tricks for a hassle-free trip through security. Watch out Portola Valley, here you come:

  • Your travel documents and ID will need to be inspected by security personnel. Have them close by so you don't have to dig around for them.
  • Your coat, belt, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic devices also need to go through the scanner.
  • Any liquids or gels, such as shampoo or hairspray, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), zip-lock bag.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to extra screening.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, pack them in your checked baggage.
