Do you have any tips for my flight to San Diego?
Depending on where you're coming from, your trip to San Diego could be a breeze or it could go on forever. Here are some tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

  • It's simple — first, put in your passport, travel docs, cash and daily medications. Next, you'll need some entertainment to while away the time. A juicy book and a phone filled with your favourite movies are good options. If you plan to catch up on some sleep, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable goods, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and pick flat, slightly roomy shoes like slip-ons.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to San Diego?
It's all about being organised. We've pulled together some tips and tricks for a fuss-free trip through airport security. Watch out San Diego, here you come:

  • Your boarding pass and passport will need to be presented to airport security. Keep them handy so you don't hold up the queue.
  • Your jacket, belt, keys and other items in your pocket, like your earphones, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic devices will need to go through the scanner.
  • Any gels or liquids, such as toothpaste or perfume, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a possibility that you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, pack them in your checked baggage.
