Do you have any tips for my flight to Ottawa?
We've rounded up all the info you need to make your journey an enjoyable experience. Follow our tips and you'll be breezing through the airport and discovering Ottawa in next to no time. What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to pack in advance. Start with the essentials: passport, boarding pass, cash and important medications. Next, take on board items that'll help keep you busy, like some electronic devices or a thrilling book. It's also wise to pack your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, be sure to squeeze in toiletries like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects hiding in one of the zippers of your carry-on luggage. Other prohibited items include explosive or flammable substances, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear during your flight. Loose clothing is a sensible option, as are enclosed shoes like sneakers.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression tights or socks and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Ottawa?
Being organised before you get to the airport can make your getaway to Ottawa a breeze. We've compiled some top tips for a swift journey past security:

  • Be sure to keep your ID and travel documents within easy reach. They're the first things you'll be asked for by airport security.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
  • All your electronic gadgets, including your phone and laptop, will also need to be scanned.
  • Want to bring along your favourite cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you on board.
  • It's also likely that you'll be asked to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Airlines won't allow any sharp items or pocket knives in the cabin. If you must bring these kinds of items, put them in your checked luggage.
