Frequently asked questions
How to book the cheapest flight to San Francisco?
Do you have any tips for my flight to San Francisco?
- First and foremost, put in your passport, important documents, wallet and vital medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy book and a phone crammed with your favourite movies are some fantastic options. If you plan to catch more than just forty winks, a neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you touchdown looking and feeling fresh.
- Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your precious pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and strong acids, are also restricted.
- You'll want to choose comfort over style. Prepare for changes in temperature by dressing in layers, and pick slightly roomy, flat footwear like slip-ons.
- Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some gentle exercises in your seat to improve your circulation.
How to get through airport security fast when flying to San Francisco?
- Security personnel first need to make sure that you have a valid ID and travel documents before anything else. Keep them within easy reach.
- The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
- For just a few moments, you'll need to unplug from the digital world. Your tablet, phone and any other electronic devices will need to go through the scanner.
- Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
- There's a chance you'll be asked to remove your shoes for scanning, so wearing slip-on sneakers is always a good idea.
- Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, pack them in your checked luggage.
