  • Airport security staff will ask to see your travel ID and boarding pass as part of their checks. Store them in an accessible place, so they’re ready for inspection.
  • Belts, wallets and wrist watches are to be placed in a bin for X-raying. If you pass through the body scanner with any one of these items, you’ll be turned back and instructed to remove them.
  • Laptops and other electronic devices must be placed in a tray to be X-rayed.
  • When you get to the security checkpoint, you’ll be asked to place all creams, gels and liquids in a separate tub for inspection. Make sure they’re all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Untie your shoelaces as you approach the body scanner. Depending on the sort of shoes you’re wearing, security may ask you to take them off.

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.
