This can happen occasionally because it’s not possible for us to show live prices until the actual booking time, as flight prices and availability are constantly changing. The prices shown on these pages are based on recent prices found by other users on our site over the past four days. For this reason, the prices we show on these search pages are only an estimate, which is why we state “indicative prices only” on the month view page.
Once you input a specific departure point, destination, and date, we always display the most recently available price on the final page. At that point, you can choose to be transferred to the airline or travel agent’s website to complete the booking at that price.
We are constantly working on improving the accuracy of our month view prices, as it is in our own interests as well as our customers for them to be as accurate as possible.
