The prices you see are built from the live cost of the travel product plus any taxes and charges that apply, and they are shown to you before you commit. We aim to put the full, honest figure in front of you on the page rather than adding mystery costs at the final step.
Travel pricing moves, sometimes quickly, because airlines and hotels change their own rates through the day. That means a price you saw yesterday may not be the price today, which is normal across the whole industry and not unique to us.
Because of this movement, the price is only truly fixed once your booking is confirmed and paid. If you are watching a particular trip, booking when the number looks right to you is usually wiser than waiting for it to fall, since it can just as easily rise.
