How to survive the flight to San Diego?
We’ve pulled together all the info you need to make your journey as pain-free as possible. Follow our tips and you’ll be hightailing it through the airport and exploring San Diego in no time at all.What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you’ve got all the right gear. First things first, you’ll need toiletry items, such as a toothbrush and some deodorant, a fresh set of clothes and something to read. Secondly, find room in your hand luggage for your mobile phone, a charger, your medications and perhaps a proper neck pillow too. Last, but definitely not least, be sure to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have sharp objects (like a knife or scissors) lurking in your carry-on luggage. Other restricted items include explosive or flammable substances, such as aerosol cans and fuel, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The narrow aisles of your plane are not the place for a fashion parade. Don comfortable layers and don’t forget to bring a sweater as it tends to get cool in the cabin. Flat, enclosed shoes are also a sensible choice.
  • You’ve probably heard about DVT (deep vein thrombosis), a blood clotting condition caused by long periods of sitting. There are numerous ways to lower your risk. Don a pair of compression tights or socks, drink plenty of water and move your legs and feet. Walk around the cabin when possible or perform exercises in your seat.

How to get through airport security fast when flying to San Diego?
The trick is to be organised before you get to the airport security gate. That way, you’ll be stepping onto that plane to San Diego in a flash. Follow these tips and get your trip off to a great start:

  • Security personnel first need to make sure that you have a valid passport and matching boarding pass before you’re allowed to proceed any further. Keep them close by.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They’ll all need to go on the X-ray conveyor belt.
  • Electronic devices like laptops and phones will also have to go through the machine for inspection. Don’t worry though, you’ll be back online before you know it.
  • Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a good footwear choice as you’re less likely to be asked to remove them when passing through security. Boots and other heavy shoes are usually subjected to additional screening.
  • Knives and other sharp items can’t be taken on board. They’ll be seized at security, so pack them safely away in your checked bags.
