Do you have any tips for my flight to Onex?
We've pulled together all the info you need to make your flight a stress-free experience. Follow our tips and you'll be breezing through the airport and having a ball in Onex in no time flat. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, official ID, cash and vital medications. Next, you'll want some extra in-flight entertainment to help pass the time. A thrilling novel and a phone filled with your favourite shows are some fantastic options. If you hope to catch forty winks, a comfy neck pillow and a pair of earplugs will also be useful. Finally, make room for a few toiletry items to ensure you step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable substances, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your priority is to be as comfortable as you can. Go for a pair of slip-on shoes, dress in loose, natural fibers and remember to take a jacket in case it gets chilly in the cabin.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, drink lots of water, consider wearing compression tights or socks and keep your legs and feet moving.

How to get through airport security fast when flying to Onex?
The answer is simple — be prepared. We've pulled together some useful tips for an easy trip through airport security. Look out Onex, here you come:

  • First things first. Your travel ID and boarding pass will need to be inspected by airport security personnel. Keep them someplace accessible so you don't hold up the queue.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Personal belongings like your coat, belt and earphones need to go through the machine.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry, you'll be back online before you know it.
  • Remember to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when going through security. Hiking boots and heavier-style shoes are often 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 in the cabin.
