Do you have any tips for my flight to Ontario?
We've got the lowdown on how to make your journey as stress-free as possible. Follow our top tips and you'll be cruising through airport security and exploring Ontario in no time. What to pack in your hand luggage:

  • It's easy — first, pack in your passport, travel docs, cash and daily medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a tablet crammed with your favorite movies are good options. If you plan to take a short snooze, a neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, blades, spray paint and flares. Sporting equipment like ski poles, and items that could harm other people, such as pepper spray and firearms, won't be allowed on board either.

What to wear on a flight:

  • Comfort should be your main priority when deciding what to wear during your flight. Loose clothing is a smart choice, as are flat, slip-on shoes.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Ontario?
Being prepared before you arrive at the airport will help make your getaway to Ontario quick and painless. Read through our useful tips for a stress-free journey past security:

  • Keep your ID and boarding pass within easy reach. They're the first items you'll be asked to present to security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online in no time.
  • Don't forget to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be 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 a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed on board.
