Do you have any tips for my flight to San Francisco?
Depending on where you're coming from, your journey to San Francisco could be a breeze or it could go on forever. We've put together some useful tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • Flying can be a stress-free experience if you pack the right things. Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a spare pair of socks and a few magazines. Secondly, make room in your hand luggage for your electronic devices, chargers, any medications and perhaps a proper neck pillow too. Lastly, remember to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, drills, aerosol cans and flares. Sporting equipment like baseball bats, and items that could injure passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

  • Your top priority is to feel as comfortable as possible. Opt for flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to take a jacket in case you get chilly in the cabin.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by drinking water, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to San Francisco?
Being organized before you get to the airport will help make your getaway to San Francisco a piece of cake. Here are some handy tips for a stress-free journey past security:

  • Be sure to keep your travel documents and ID at hand. They're the first items you'll be asked to show at security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronic gadgets also need to be sent through the scanner.
  • Remember to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when going through security. Boots and other heavy-style shoes are often subjected to additional screening.
  • Pocket knives and other sharp items are not allowed on board. They'll be seized at security, so put them in your checked suitcase.
