Frequently asked questions

• What is the cheapest day of the week to book a flight?

  The best day to book your flight depends on a number of factors, but there are general trends that you can follow to increase your chances of cheaper plane tickets. Based on an analysis of KAYAK data for all flights departing from inside Canada over the last 12 months, the cheapest day to fly for domestic flights is Thursday. For international flights, Wednesday had the cheapest tickets on average.

• Which month of the year are flight prices lowest?

  It’s well established that flights in the low season are generally cheaper than ticket prices during the high season. That means that knowing which month to find the lowest priced plane tickets will depend heavily on seasonality and your destination. While avoiding peak travel times can help you keep costs down, our data shows that the month with the lowest priced plane tickets for domestic flights based on all searches made on KAYAK in the last 12 months was January, while the most expensive was August. If you’re booking an international flight, then June is the cheapest month to fly and December the most expensive.

• When is the best time to buy plane tickets - Last minute or in advance?

  Last minute flight deals are definitely up for grabs but when exactly to purchase your plane tickets will depend on where you’re traveling to and from. Based on all data for flight searches made on KAYAK over the last 12 months, prices for domestic flights remained below the average price up to 1 weeks before departure. For international flights, deals could still be had up to 1 weeks prior to the departure date, with prices remaining below average. If you’re flexible, KAYAK brings you both advance and last minute one-way and round-trip flight deals.

• Can flying international flights with a layover save money on airfare?

  For many long-haul international flights, flying direct is not possible and you will have to fly with a layover. Some routes will offer both and you could consider flying with a layover for a number of reasons. Firstly, breaking up what would otherwise be a long-haul flight, taking a rest and then completing the journey might make the flight more manageable. Secondly, prices can also be lower than direct flights, so while it might take longer for you to reach your destination, you could save money. We’ve looked at prices over the last 12 months for the 100 most popular international destinations for KAYAK users and on average, prices for non-stop flights were cheaper than flights with a layover.
