Do you have any tips for my flight to Sunnyvale?
Depending on where you're coming from, your journey to Sunnyvale could be completely stress-free or it could drag on forever. Below are some tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:
  • The secret to having a hassle-free flight experience is to pack in advance. So, let's start with the essentials: passport, official ID, cash and important medications. Next, bring items that'll help keep you entertained, like some electronic gadgets or a few magazines. It's also wise to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, be sure to toss in toiletries like a toothbrush, cleansing wipes and a fresh set of clothes.
Do not pack the following items in your hand luggage:
  • Make sure you don't have a sharp object lurking in one of the compartments of your hand luggage. Other banned items include flammable or explosive substances, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your main concern when choosing what to wear on your flight. Loose, breathable clothing is a sensible option, as are flat, closed-toe shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Sunnyvale?
The simple answer is — be prepared. We've pulled together some helpful hints for an easy trip through airport security. Look out Sunnyvale, here you come:
  • Airport security personnel first need to know that you have a valid passport and matching travel documents before anything else. Have them in your hand, ready for inspection.
  • Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
  • For just a few moments, you'll need to unplug from technology. Your phone, laptop and any other electronic gadgets will need to be sent through the scanner.
  • Remove liquids and gels from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines won't allow any sharp or pointed objects in your hand luggage. If you must bring these kinds of items, pack them in your checked luggage.
