I think Orbitz (a major website) do cache their flight search results. Last time I purchased a ticket, they kept on showing me the same flights. However, when you clicked on some of them, they will tell you (in a next screen) that they were no seats available.
I guess it is a matter of how you balance your customer satisfaction. Orbitz has too many queries (most of the people just try to look for cheap tickets). So, they will cache the results to maintain the bulk of their audience happy. However, if you want to give real online experience, I would not recommend doing so.

Since seats and flight status can change from one second to another, they are not good candidates to be cached. What do you think? I wonder how people cache flights.
