How to survive the flight to San Diego?
We’ve rounded up all the info you need to make your flight a pleasant experience. Follow our tips and you’ll be hightailing it through airport security and having a ball in San Diego in no time flat.What to pack in your hand luggage:

  • A plane ride can be easy if you’ve got all the right things. First of all you’ll need toiletry items, such as deodorant and a toothbrush, a fresh change of clothes and a magazine or two. Secondly, find room in your hand luggage for your laptop, a charger, medications and maybe a cosy neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, fuel and fireworks. Sports equipment like baseball bats, and objects that could injure passengers, such as firearms and ammunition, can’t come on board with you either.

What to wear on a flight:

  • The aisles of your airplane are not the place for a fashion parade. Layer yourself up with comfortable clothes and don’t forget to bring a sweater as it can get quite cool in the cabin. Closed-toed, flat shoes are always a good idea too.
  • Most travellers are aware of DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are numerous ways to mitigate your risk. Wear a quality pair of compression socks or tights, stay well hydrated and move your legs and feet. Walk around the cabin when possible or try out some exercises in your seat.

How to get through airport security fast when flying to San Diego?
The secret is to be organised before you arrive at the security gate. That way, you’ll be boarding that plane to San Diego in next to no time. Follow these tips and get your holiday off to a fantastic start:

  • Airport security personnel first need to determine that you have a valid ID and travel documents before you can proceed any further. Have them in your hand, ready for inspection.
  • Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • All electronic gadgets, including your tablet and phone, will also need to be separately scanned.
  • Remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a clever footwear choice as you’re less likely to be asked to remove them when passing through security. Boots and other heavy-style shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won’t be allowed on board.
