Frequently asked questions

How to book the cheapest flight to San Francisco?
If you want to have some extra spending money on your trip to San Francisco, then listen up! As any experienced jet-setter will tell you, avoid booking at the last minute. Airfares are generally more expensive close to the departure date. Also, look around online and compare your options. If your destination has several airports, you may be able to score a better deal by flying into one a little further out. Last of all, be ready to secure your seat quickly if you stumble on a great deal. It might not stick around for too long. With a bit of knowledge and some luck, the ideal airfare will be yours.
Do you have any tips for my flight to San Francisco?
No matter where you're coming from, flying can be a seamless experience if you're well prepared. We've compiled a list of top travel tips that will get your San Francisco holiday started on the right note. What to pack in your hand luggage:
  • Air travel can be easy if you carry the right gear. Firstly, you'll need toiletry items, such as a toothbrush and some deodorant, a spare set of clothes and something to read. Secondly, make room in your bag for your phone, tablet and chargers, your medications and maybe a neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and your credit cards.
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 suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your Swiss Army knife, and products which are explosive or flammable, such as spray paint, flares and poisons, are also not allowed.
What to wear on a flight:
  • Your aim is to feel as comfortable as possible. Opt for flat, closed-toe shoes, dress in loose, breathable clothing and remember to bring a jacket in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.
How to get through airport security fast when flying to San Francisco?
Being organised before you arrive at the airport will help make your trip to San Francisco quick and painless. We've compiled some handy hints for a stress-free journey past security:
  • First things first. Your passport and boarding pass will need to be presented to airport security. Keep them within easy reach to avoid fumbling around for them.
  • Your belt, jacket, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Any liquids or gels, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
