Mineta San Jose International Airport (SJC). SFO is located 13 miles south of downtown, OAK sits 21 miles southeast of the city across the bay, while SJC is 45 miles southeast of San Francisco. SFO and OAK airports are often the most popular choices because of their close proximity to the San Francisco, California, attractions.

If you’ve booked flights to San Francisco through SFO, you’ll find a number of on-site amenities at the terminals. Fuel your hunger at one of the many cafes, fast food places, and restaurants, and then get your retail fix at the various designer boutiques, book stores, and souvenir shops. The SFO terminals even feature Kids’ Spots, where your little ones can burn off some energy before their next flight. For additional information about San Francisco Int.

How to survive the flight to San Francisco?
We’ve got the lowdown on how to make your flight as stress-free as possible. Follow our tips and you’ll be breezing through the airport and exploring San Francisco in no time flat.What to pack in your hand luggage:

  • First of all, pack in your passport, travel docs, wallet and vital medications. Next, you’ll want some entertainment to while away the time. A juicy book and a phone filled with your favorite movies are some terrific options. If you hope to catch forty winks, a quality neck pillow and some noise-canceling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp objects, like your treasured Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, flares and strong acids, are also prohibited.

What to wear on a flight:

  • The long, narrow aisles of your airplane are no fashion runway. Layer up with comfortable clothing and bring a sweater as it tends to get cool in the cabin on long-haul flights. Slightly roomy, flat shoes are always a good choice too.
  • Unfortunately, a risk of long flights is developing deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity. To prevent this from happening, make the most of every opportunity to walk around and give your legs a stretch. Compression tights and socks are another easy way to help reduce this risk.

How to get through airport security fast when flying to San Francisco?
As seasoned travelers know, the secret is to be well prepared before you arrive at security. That way, you’ll be boarding that plane to San Francisco in next to no time. Follow these helpful tips and get your vacation off to a flying start:

  • Your travel documents and passport will need to be presented to airport security. Keep them at hand so you don’t hold up the line.
  • Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
  • Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. Don’t worry though, you’ll be back online in no time.
  • Don’t forget to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
  • It’s also likely that you’ll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won’t be allowed on board.
