Do you have any tips for my flight to Ontario?
If you're poorly prepared, air travel can be daunting. But there's no need to worry. Follow these handy hints and enjoy a comfortable start to your time in Ontario. What to pack in your hand luggage:

  • A plane trip can be a cruisy experience if you bring the right things. First of all you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a good read. Next, find a spot in your hand luggage for your phone, tablet and chargers, your important medications and maybe a blow-up neck pillow as well. Lastly, remember to take your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, spray paint and fireworks. Sporting equipment like ski poles, and items that could injure passengers, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • Your goal here is to feel as comfortable as possible. Choose a pair of slip-on shoes, dress in loose, natural fibers and remember to bring a sweater in case you get chilly in the cabin.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long-haul flights. Reduce the risks by drinking water, keeping your feet and legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Ontario?
The secret is to be organized before you arrive at airport security. That way, you'll be boarding that plane to Ontario in next to no time. Follow these tips and get your vacation off to a flying start:

  • First things first. Your travel documents and ID will need to be inspected by airport security. Have them easily accessible so you don't hold up the line.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your phone and tablet, are also required to be scanned separately.
  • Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Sharp items such as knives and scissors are not allowed on board. They'll be seized at security, so pack them in your checked suitcase.
