Several days ago I wrote about an application I'd like to see and lamented about the functionality of the RSS implementations at Expedia and Travelocity.
Not long after the post, I found myself filling up on a crow sandwich - Steve Miale, Expedia's Program Manager/Developer for RSS Feeds contacted me and set me straight.
With Expedia, you can subscribe to fares from a single origin without specifying a destination. Here's my feed for fares from DFW. And, Steve also sent along a hack for multiple destinations - this one's for Phoenix, Albuquerque, Tampa, and Las Vegas all from DFW.
Sadly, none of the fares I'm getting are low enough to get me to the airport, but it's working just as Steve said it would. I may not like the fares I'm getting but that's not Steve's problem.
