I think that owning ITA allows them to have more data to mine/predict and better access but it doesn't explain how fast the searches are. Most airfare searches still hit GDSs which are relatively slow to respond. The only way I can think of Google can deliver such a performance is by intelligently pre-caching airfare searches. Google?
