The age-old question on every traveler's mind: what's the best day to buy plane tickets? For years, we've been told that Tuesdays and Wednesdays are the days to snag the best deals, but is that really true? In this article, we'll dive into the science behind airline pricing and reveal the best days to book your flights.
The Science of Airline Pricing
Airlines use complex algorithms to determine their ticket prices, taking into account factors like demand, fuel prices, and seasonal fluctuations. They also employ a pricing strategy called "yield management," which involves adjusting prices based on the number of seats available and the time of booking.
The Importance of Demand
Demand is a critical factor in determining airline ticket prices. During peak travel seasons, such as summer vacation or holidays, demand is high, and prices tend to increase. Conversely, during off-peak seasons, demand is lower, and prices may decrease. Airlines also take into account special events, like festivals or sporting events, which can drive up demand and prices.

The Best Days to Buy Plane Tickets
So, what are the best days to buy plane tickets? The answer may surprise you. According to a study by Skyscanner, the best day to book a flight is actually Saturday. That's right, Saturday! On this day, prices tend to be 6% lower than on other days of the week. Here are the top 5 best days to buy plane tickets, based on the study:
- Saturday (6% lower than average)
- Monday (5% lower than average)
- Wednesday (4% lower than average)
- Friday (3% lower than average)
- Thursday (2% lower than average)
It's worth noting that these results may vary depending on your destination and travel dates. However, in general, these days tend to be the best for finding deals.
Why Saturday is the Best Day to Buy Plane Tickets
So, why is Saturday the best day to buy plane tickets? There are a few reasons. Firstly, many business travelers book their flights on Mondays, which drives up demand and prices. By contrast, Saturdays tend to be a slower day for business travel, resulting in lower demand and prices. Secondly, airlines often adjust their prices on weekends, which can lead to discounts and deals.

Booking in Advance vs. Last-Minute Booking
Another important factor to consider is the timing of your booking. Booking in advance can often lead to better deals, but it's not always the case. A study by Kayak found that booking flights 54 days in advance tends to result in the best prices. However, booking too far in advance can also lead to higher prices. Here's a rough guide to booking in advance vs. last-minute booking:
| Booking Time | Price Difference |
|---|---|
| 54 days in advance | -$20 |
| 21 days in advance | -$10 |
| 7 days in advance | -$5 |
| Last-minute booking | +$10-$20 |
As you can see, booking in advance can often lead to better deals, but it's essential to compare prices and adjust your booking time accordingly.
Conclusion (Not Really!)
While there's no one-size-fits-all answer to the best day to buy plane tickets, our research suggests that Saturdays and Mondays are generally the best days to find deals. Additionally, booking in advance and being flexible with your travel dates can also lead to better prices. Remember, the key to finding the best deals is to be informed and flexible. Happy travels!
