Do you have any tips for my flight to Ontario?
We've rounded up all the info you need to make your flight as pain-free as possible. Follow our tips and you'll be speeding through airport security and enjoying Ontario in next to no time. What to pack in your hand luggage:

  • It's simple — first, pack in your passport, official ID, cash and vital medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling book and a phone filled with your favorite shows are some great options. If you intend to catch forty winks, a neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a toothbrush and some facial wipes so you'll touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects hiding in one of the zippers of your hand luggage. Other banned items include flammable or explosive substances, such as bleach and fuel, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your main priority is to feel as comfortable as possible. Opt for flat, closed-toe shoes, dress in loose, natural fibers and don't forget to bring a jacket in case it gets cold in the cabin.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Ontario?
Being organized before you arrive at the airport can make your trip to Ontario easy and painless. Below are some useful tips for a swift journey past security:

  • First things first. Your travel ID and boarding pass will need to be shown to airport security personnel. Have them easily accessible so you don't hold up the queue.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items like your belt, coat and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • The right choice of footwear can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Sharp items like knives are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked bags.
