Living in a period with many changes and difficult to make predictions, we must, finally, learn to read the data and extract information. Analyzing the reservation data of HotelAvailabilities channel manager over the last five years, regarding the booking window, when the tourists make their reservations, we can come into useful conclusions.

Looking at the graph, we observe that in some years, which are not continuous, the behavior of travelers seems to be the same. Starting from last year (2021), which was clearly a very special season for the tourism, we see an identification with the year 2019 (record year for tourism in Greece). But if we look at the year 2020, where it was the most difficult.
And what do we need this for? Someone could wonder! We need to look at the patterns and adjust our pricing policy as well as direct marketing campaigns to the right markets depending on the season and when they book. Purchasing behavior can be adjusted and changed slightly, with different situations and events, but it does not change completely. This means that we can have at least the minimum information that will help us in maximum efficiency, both in advertising and pricing.
