How to survive the flight to Costa Mesa?
No matter where you're coming from, flying can be a seamless experience if you've prepared well enough. Check out these essential travel tips that will help get your Costa Mesa escape started on the right note.What to pack in your hand luggage:

  • Air travel can be a great experience if you bring the right gear. Firstly, you'll need toiletry items, such as deodorant and a toothbrush, a clean set of clothes and something to read. Secondly, find a spot in your bag for your electronic gadgets, chargers, any medications and perhaps a blow-up neck pillow as well. Lastly, be sure to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects hiding in the bottom of your hand luggage. Other prohibited items include explosive or flammable products, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The goal here is to feel as comfortable as possible. Dress in loose, natural-fibre clothing and bring a pullover in case it gets cool in the cabin. Pick a pair of well-fitting, flat shoes as your feet may swell a little during the journey. Leave the stilettos and heavy boots in your luggage.
  • You've probably heard about DVT (deep vein thrombosis), a blood clotting condition caused by long periods of sitting. There are numerous ways to lessen your risk. Wear a quality pair of compression socks or tights, stay hydrated and move your legs and feet. Walk the aisles of the cabin or perform exercises in your seat.

How to get through airport security fast when flying to Costa Mesa?
Being organised before your flight will help make your trip to Costa Mesa a breeze. Check out our handy tips for a speedy journey through security:

  • Be sure to have your boarding pass and ID within easy reach. They're the first things you'll be asked to show at security.
  • Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items such as your belt, coat and earphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronic devices will need to go through the scanner.
  • Any gels or liquids, such as toothpaste or perfume, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when passing through security. Boots and heavier-style shoes are usually subjected to extra screening.
  • Take all prohibited items out of 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.
