  • Keep your travel ID and boarding pass easily accessible. They’ll be the first things you’ll be instructed to produce by security personnel.
  • You’ll have to place your music on pause for a little while. Earphones and headphones must be taken off and put in a tub to be X-rayed. The same applies to items such as keys and coins.
  • Electronic devices such as tablets, laptops and phones need to be sent through the X-ray machine separately. Make sure they’re easily accessible.
  • When you get to the security checkpoint, you’ll be asked to put all gels, liquids and creams in a separate tub for scanning. Make sure they’re all in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Loosen your shoelaces before approaching the body scanner. Depending on the style of shoes you’ve got on, security may ask you to take them off.
  • Some countries have stringent quarantine laws. Think about where you’re journeying to and whether or not it’s permissible to fly with fresh fruit and other foods.

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.
