How far in advance to book flights and what are the best days to get cheap rates

Nowadays Internet has made it easier than ever to book your flights but it can still be a painful and stressful experience. You don’t want to pay a high price to see the same ticket at a lower price just a few days later. In this article we will teach you how and when to find the best flight deals. 


How far in advance should I book my flight?

First of all, it all depends if you’re booking a domestic (flights within the US and EU) or an international flight. According to a study conducted by Expedia and the Airlines Reporting Corporation (ARC), you should start booking your domestic flights as of 50 to 100 days before departure. If you’re flying overseas, then you should plan even further ahead, ideally between 150 and 225 days in advance. Note that the best deals for international routes were found around day 171.

Needless to say that the closer you get to your scheduled departure date, the higher the rates. As of 3 weeks prior to departure, flight rates start to peak. Why is it so hard to find some cheap, last-minute flights? The answer is simple: Selling 5 seats at €500 is much more profitable for an airline than selling the last 20 seats at only €100.

The below table clearly indicates us that flights booked more than 3 weeks in advance represent a significant cost saving:

What are the best days of the week to book my flight?

Generally speaking, weekends are the best time to book your tickets with Sunday being by far the best day of the week and Friday the worst. This is largely influenced by business travelers, who tend to buy their tickets at the end of the week. Sunday savings is a global trend that can be found whatever your departure city might be. 

Let’s have a look at the below graph and table: The lowest rate for travelers departing from Europe and traveling to other destinations in Europe were found on Sunday, with savings up to 30%. Sunday bookings from Europe can save you up to 13% for flights to Asia and up to 22% for flights to the US.

Please note that although the percentages slightly vary, the same trend was found for other regions.
