Do you have any tips for my flight to El Cajon?
Depending on where you're coming from, your journey to El Cajon could be a breeze or it could drag on forever. We've put together some handy travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • Firstly, and most importantly, pack your passport, travel docs, credit cards and medications. Next, you'll need some entertainment to while away the hours. A juicy book and a phone crammed with your favourite movies are always good options. If you hope to take a quick nap, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some deodorant so you'll hop off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, pocket knives, fireworks and fuel. Sports equipment like golf clubs, and items that could harm other people, such as guns and swords, are also banned from the cabin.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Choose a pair of slip-on shoes, dress in loose, breathable clothing and don't forget to take a jacket in case it gets chilly in the cabin.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Lower your risks by staying hydrated, keeping your legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to El Cajon?
Being organised before you get to the airport can make your getaway to El Cajon a piece of cake. Below you'll find some handy hints for a speedy journey through security:

  • Your travel ID and boarding pass will need to be presented to security personnel. Have them close by so you don't have to dig around for them.
  • Your belt, coat, keys and other contents of your pockets, like coins, 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 your electronics, including your tablet and phone, must also be scanned separately.
  • Don't forget to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other bulky shoes are usually subjected to extra screening.
  • Pocket knives and other sharp items can't be taken on board. They'll be confiscated at security, so pack them in your checked bags.
