American Airlines using DWR
So you begin here:
And you then get the standard airline search screen. But with a new "Price and Schedule" feature. Pick that ...
The results page uses DWR to fetch extra details on a flight.
Update: I've just spoken to Steven Leija who leads the Ajax effort (he blogged about it here), apparently, the development was very smooth, and the feature is getting great feedback. Thanks for the heads-up Steven.
I've said this before, but it bears repeating - DWR is fantastic as a way to add Ajax features to an existing website without re-writing the whole thing from scratch. Walmart is another great example of this.
It's one more step on the road to total world domination that I talked about with Marla Parker over at java.net.
