How to survive the flight to Ontario?
If you’re not prepared, air travel can be daunting. But there’s no need to hit the panic button just yet. Follow these helpful hints for a comfortable start to your vacation in Ontario.What to pack in your hand luggage:

  • First of all, pack in your passport, official ID, cash and medications. Next, you’ll need some extra in-flight entertainment to while away the hours. A juicy novel and a laptop filled with your favorite shows are some fantastic options. If you intend to catch up on some sleep, a comfy neck pillow and some noise-canceling headphones will also come in handy. Finally, find room for a few toiletry items to ensure you hop off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your treasured Swiss Army knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and fireworks, are also restricted.

What to wear on a flight:

  • The main aim is to make yourself as comfortable as you can. Layer yourself up in breathable clothing and pack a sweater in case it gets cold in the cabin. Always opt for flat, slightly roomy shoes as your feet may swell a little during the journey. Leave the stilettos and heavy hiking boots in your checked luggage.
  • Most of us have heard about DVT (deep vein thrombosis), a blood clot condition caused by prolonged periods of sitting. There are numerous ways to reduce your risk. Wear a good-quality pair of compression socks or tights, drink lots of water often and move your legs and feet. Walk the aisles of the cabin or try out some exercises in your seat.

How to get through airport security fast when flying to Ontario?
It’s simple — be prepared. We’ve put together some handy tips and tricks for a stress-free trip through security. Look out Ontario, here you come:

  • Keep your passport and boarding pass easily accessible. They’re the first things you’ll be asked to present to airport security.
  • After that, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items such as your coat, belt and headphones need to go through the machine.
  • For just a few minutes, you’ll need to unplug from technology. Your phone, tablet and any other electronic gadgets will need to be sent through the scanner.
  • Can’t travel without your favorite 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 clear zip-lock bag, you can bring it with you in your carry-on.
  • There’s a possibility that you’ll be required to take your shoes off to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Sharp items like knives are prohibited in the cabin. They’ll be seized at security, so pack them safely away in your checked suitcase.
