Do you have any tips for my flight to Onex?
We've got the lowdown on how to make your journey as stress-free as possible. Follow our tips and you'll be hightailing it through the airport and discovering Onex in no time flat. What to pack in your hand luggage:

  • First of all, pack your passport, travel docs, wallet and vital medications. Next, you'll need some extra in-flight entertainment to while away the hours. A juicy novel and a tablet filled with your favourite movies are some terrific options. If you intend to catch up on some sleep, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some cleansing wipes to ensure you hop off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your precious pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, spray paint and matches, are also restricted.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on your flight. Loose, breathable clothing is a smart option, as are roomy, closed-toe shoes.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Onex?
Being organised before you arrive at the airport can make your trip to Onex a breeze. Below are some useful tips for a speedy journey past security:

  • Your passport and boarding pass will need to be inspected by airport security. Keep them handy so you don't hold up the queue.
  • Your belt, jacket, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronics also need to be sent through the scanner.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • It's also possible you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board.
