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

  • Air travel can be a great experience if you've got all the right things. First of all you'll need basic toiletries, such as lip balm and hand cream, a spare change of clothes and a few magazines. Next, find room in your carry-on bag for your phone, tablet and chargers, any vital medications and maybe a comfy neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, knives, fireworks and fuel. Sporting equipment like ice skates, and items that could injure passengers, such as swords and batons, aren't allowed in the cabin either.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and opt for flat, easy-to-remove shoes like slip-ons.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long flights. Lower your risks by staying hydrated, keeping your feet and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to San Diego?
The answer is — be prepared. We've put together some helpful hints for an easy trip through airport security. Look out San Diego, here you come:

  • Your travel documents and passport will need to be shown to airport security personnel. Keep them at hand so you don't hold up the queue.
  • Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Items like your belt, coat and headphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Any gels or liquids, such as toothpaste or perfume, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • There's a chance you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a good idea.
  • Airlines will not allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, put them in your checked baggage.
