Do you have any tips for my flight to Adelanto?
Depending on where you're coming from, your trip to Adelanto could be simple and straightforward or it could drag on forever. Below are some useful hints that will help you start your next great escape on the right foot. What to pack in your hand luggage:
  • First, pack your passport, official ID, bank cards and vital medications. Next, you'll want some extra in-flight entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite movies are good options. If you intend to catch up on some sleep, a comfy neck pillow and some earplugs will also come in handy. Finally, leave some space for a toothbrush and some deodorant so you'll arrive at your destination feeling fresh as a daisy.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have a sharp object lurking in one of the compartments of your carry-on luggage. Other restricted items include explosive or flammable goods, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your main concern when deciding what to wear on board. Loose clothing is a sensible choice, as are flat, closed-toe shoes.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression socks and keep your legs and feet moving.
How to get through airport security fast when flying to Adelanto?
A little pre-planning before your flight will make your getaway to Adelanto a pleasure. We've rounded up some useful tips for a stress-free journey past security:
  • Security personnel first need to verify that you have a valid passport and travel documents before anything else. Have them ready to show.
  • After that, both you and your hand luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your belt, coat and earphones need to go through the machine.
  • All your electronic gadgets, including your tablet and phone, must also be scanned.
  • Can't travel without your favourite cologne or perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can bring it with you on board.
  • There's a chance you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a good idea.
  • Take all prohibited items out of 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.
