How to survive the flight to San Diego?
If you’re not prepared, air travel can be tough. But don’t hit the panic button just yet. Follow these helpful hints for a stress-free start to your vacation in San Diego.What to pack in your hand luggage:

  • The secret to having a great travel experience is to pack ahead. So, let’s start with the basics: passport, travel documents, cash and any vital medications. Next, take on board items that’ll help pass the time, like your laptop or a few magazines. It’s also smart to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have a Swiss Army knife hiding in your carry-on luggage. Other restricted items include explosive or flammable goods, such as fuel and matches, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort really should be your highest priority when choosing what to wear during your flight. Consider your choice of footwear carefully too, as swollen feet are quite common. Slightly roomy, flat shoes are always a smart option.
  • It’s likely you’ve heard about deep vein thrombosis (DVT), a blood clot condition caused by reduced mobility or inactivity. There are many ways to lessen your risk. Wear a good-quality pair of compression socks or tights, drink lots of water and remember to keep your legs and feet moving. Wander around the cabin or perform some simple exercises in your seat.

How to get through airport security fast when flying to San Diego?
The trick is to be well organized before you get to the security gate. That way, you’ll be stepping onto that plane to San Diego in no time flat. Follow these tips and get your trip off to a fantastic start:

  • First things first. Your boarding pass and passport will need to be shown to airport security personnel. Keep them within easy reach so you don’t have to dig around for them.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • All your electronics, including your tablet and phone, are also required to be separately scanned.
  • Any liquids or gels, such as shampoo or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-lock bag.
  • The right choice of footwear can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Sharp items are not allowed on board. They’ll be confiscated at security, so pack them in your checked luggage.
