How to survive the flight to Ontario?
No matter where you're coming from, flying can be a seamless experience if you're well prepared. We've made a list of top travel tips that will get your Ontario escape started on the right note.What to pack in your hand luggage:

  • A plane trip can be a great experience if you take the right things. Firstly, you'll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a spare pair of socks and a magazine or two. Next, find room in your carry-on bag for your electronic gadgets, chargers, your medications and perhaps a proper neck pillow as well. Lastly, be sure to bring your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as spray paint, flares and fuels, are also restricted.

What to wear on a flight:

  • Your aim here is to be as comfortable as possible. Layer up in natural fibers and pack a cardigan in case you get cold. Go for a pair of flat, slightly roomy shoes as your feet may swell during the flight. Leave the high heels and chunky boots in your checked luggage.
  • Unfortunately, a risk of long-distance travel is developing DVT (deep vein thrombosis), a blood clot condition caused by lengthy periods of inactivity. To prevent this, take every opportunity to wander around the cabin. Compression tights and socks are another great idea to help reduce this risk.

How to get through airport security fast when flying to Ontario?
As savvy travelers know, the secret is to be well organized before you get to security. That way, you'll be boarding that plane to Ontario in a flash. Follow these helpful tips and get your vacation off to a fantastic start:

  • Airport security personnel first need to check that you have a valid ID and travel documents before you're allowed to proceed any further. Have them within easy reach, ready for inspection.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All electronic devices, including your phone and laptop, are also required to be scanned.
  • Remember to remove gels and liquids from your carry-on luggage. 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 single quart-size (one liter), clear zip-lock bag.
  • Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when passing through security. Big boots and other heavy shoes are usually subjected to extra screening.
  • Knives and other sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked suitcase.
