Analytics have become so important today for website. And one of the most widely used is the Google Analytics for websites. However, this is more a business facing fact report of sorts.
Note: I have inverted the colors to make it snazzier :)
Cleartrip shows the Flights that ply to the destination, their cost forecast for the month and even the comparison between the airlines based on price for every day of the month. Long gaps if any show unavailability of flights on those days.
Overall, a great tool to plan in advance. Sadly, its available for domestic flights only, as yet.
