How to survive the flight to Onex?
Wherever you’re coming from, flying can be a pleasant experience if you’ve prepared well enough. Take a peek at these handy travel tips that will help get your Onex holiday started on the right note.What to pack in your hand luggage:

  • It’s easy — first, pack your passport, official ID, wallet and vital medications. Next, you’ll need some in-flight entertainment to while away the hours. A juicy novel and a laptop crammed with your favourite shows are always good options. If you intend to catch up on some sleep, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some facial wipes so you’ll arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, blades, fuel and fireworks. Sports equipment like hockey sticks, and objects that could injure passengers, such as swords and guns, aren’t allowed in the cabin either.

What to wear on a flight:

  • The aisles of your airplane are no fashion runway. Don comfortable layers and remember to take a sweater as the temperature can drop in the cabin on long-haul flights. Closed-toed, flat shoes are always a good idea too.
  • Unfortunately, one risk of long flights is developing deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity. To avoid this, make the most of every opportunity to walk around the cabin and stretch your legs. Compression tights and socks are another easy way to help lower your risk.

How to get through airport security fast when flying to Onex?
A little pre-planning before you get to the airport can make your trip to Onex a piece of cake. Below are some useful tips for a speedy journey through security:

  • Airport security personnel first need to establish that you have a valid passport and boarding pass before anything else. Have them close by, ready for inspection.
  • 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 trigger the alarm. Items like your belt, jacket and headphones need to go through the machine.
  • All your electronic gadgets, including your tablet and phone, will also need to be separately scanned.
  • Want to bring along your favourite cologne or perfume? Not a problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-lock bag, it’s fine to bring with you on board.
  • Lightweight sneakers are a great footwear choice as you’re less likely to be required to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to additional screening.
  • Sharp or pointed items are prohibited in the cabin. They’ll be confiscated at security, so pack them in your checked baggage.
