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 15 days. For this reason, the prices we show on these preliminary search pages are only an indication, which is why we state “indicative prices only” on the search results page.
Once you input a specific departure point, destination and date we always display the most recently available price on the final page, at which point you can then opt 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 preliminary search page prices, as it is in our own interests as well as our customers for them to be as accurate as possible.
