  • Belts, coins and keys are to be put in a bin for X-raying. If you enter the body scanner with any of these items, you’ll be requested to turn back and remove them.
  • All laptops must be taken out of their protective cases and placed in a tub prior to being X-rayed.
  • When you approach the security checkpoint, you’ll be asked to put all creams, liquids and gels in a separate tray for scanning. Make sure they’re all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Think about your choice of footwear. Slippers are great because they’re super easy to remove when you’re at the security checkpoint. Try wearing some on your next journey!
  • Pack any pocketknives or other sharp metal items inside your checked luggage. Security won’t allow these on the aircraft.

How to find cheap flights

What is the best day to buy a plane ticket?

Airfares offered on Friday tend to be the cheapest, according to flight demand on Travelocity.ca in 2021. Purchasing your airfares on a Thursday or Saturday can also provide better value, however our advice if you’re looking to save money is to avoid booking on a Wednesday or Sunday. Our data shows that those two days have the highest ticket values on average, so keep this in mind if you’re browsing flight deals.

 

What are the cheapest days to fly?

Frequent travellers may already know this, earlier in the week is often the cheapest time to fly. Flights departing on a Monday are the cheapest of the week. Since flights towards the middle of the week tend to be more popular, this causes the prices to rise. This is why, on average, airfares booked on Travelocity.ca in 2021 were most expensive for Wednesday departures.

 

How far in advance can you book a flight?

Here’s the deal: It is typically possible to start comparing international airfares on Travelocity.ca up to 12 months in advance. However, it does depend on the carrier as not all airlines release their prices that far out. According to our 2021 flight demand trends, last minute planners can still bag a bargain with some of the cheapest fares appearing 2-4 weeks prior to their travel dates.

*According to flight demand on Travelocity.ca from January to December 2021. Savings are subject to change and may vary depending on selections made.
