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 no sweat at all or it could drag on forever. Here are some handy travel tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

  • A plane ride can be a great experience if you pack the right things. Firstly, you’ll want a few basic toiletries, such as a toothbrush and some deodorant, a spare change of clothes and a few magazines. Next, leave space in your carry-on bag for your laptop, a charger, medications and maybe a comfy neck pillow too. Lastly, and most importantly, remember to take your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes tools, metal cutlery, spray paint and flares. Sports equipment like ski poles, and items that could harm other people, such as swords and batons, aren’t allowed in the cabin either.

What to wear on a flight:

  • Go for comfort over style. Prepare for temperature changes by wearing layers, and opt for flat, easy-to-remove footwear like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to San Diego?
The answer is simple — be organized. We’ve compiled some top tips for a fuss-free trip through airport security. Look out San Diego, here you come:

  • Be sure to keep your boarding pass and passport close by. They’ll be the first things you’ll be asked to present to airport security.
  • Your belt, jacket, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • All electronic gadgets, including your tablet and phone, must also be scanned.
  • Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you a few precious minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won’t be allowed on board.
