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

  • The secret to having a stress-free flight experience is to be prepared. Start with the essentials: passport, travel documents, bank cards and any vital medications. Next, take on board items that'll help pass the time, like some electronic devices or a good book. It's also wise to bring your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to squeeze in toiletry items like a toothbrush, facial wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, knives, spray paint and flares. Sporting equipment like hockey sticks, and items that could harm other people, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and opt for flat, enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Ontario?
As seasoned travellers know, the secret is to be well prepared before you get to the airport security gate. That way, you'll be boarding that plane to Ontario in no time flat. Follow these helpful tips and get your vacation off to a great start:

  • First things first. Your travel ID and boarding pass will need to be presented to airport security personnel. Keep them handy so you don't have to dig around for them.
  • Your belt, coat, keys and other small items, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • All your electronic gadgets, including your phone and laptop, are also required to be scanned.
  • Want to bring along your favourite perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're allowed to bring it with you in your carry-on luggage.
  • It's also possible you'll need to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a good idea.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, pack them in your checked luggage.
