I am trying to book flights for a weekend trip from Warsaw to Athens. I would like to fly after work on Friday and return Sunday evening, so I have pretty well defined flight times in terms of weekdays. I can even come up with my preferred flight numbers. The thing that is flexible is the choice of weekend. Is there a tool that could automate this search, i.e. display a table of all the weekends in some range with corresponding prices?
NOTE: This is a much more narrowed problem than a broad search, and as it turns out (see answers) it has a dedicated solution.
