Do you have any tips for my flight to Onnion?
Wherever you're jetting in from, flying can be an enjoyable experience if you've prepared well enough. We've put together a list of essential travel tips that will help get your Onnion holiday started on the right foot. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you bring the right gear. Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a clean pair of socks and a good book. Next, leave space in your bag for your phone, tablet and chargers, any daily medications and maybe a cosy neck pillow as well. Lastly, don't forget to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, flares and fuels, are also prohibited.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfy clothing and choose shoes that are enclosed, flat and easy to slip on and off.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Onnion?
It's all about being prepared. We've compiled some top tips for a speedy trip through airport security. Watch out Onnion, here you come:

  • Airport security personnel first need to see that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • Your belt, coat, keys and other contents of your pockets, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronics must also go through the scanner.
  • Any liquids or gels, such as shampoo or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Pocket knives and other sharp items are not allowed on board. They'll be confiscated at security, so pack them in your checked suitcase.
