I have noticed on some of the individual airline pages some very coarse graphic information about seasonal and current demand for airline tickets to particular destinations when selected so you can get a feel for when you are travelling and the basic price fluctuation. I would love to see this being done by more airlines, and even other industries that have seasonal fluctuating prices.
Sometimes I am more interested in going rather than the destination. I don’t need to know the cost to a particular destination, I just want to know I’m getting a good deal. I figure more people will travel then currently travel during off-peak times, and to a greater variety of places.
