Book With Matrix actually helped me "shake" a cheaper fare loose a few weeks ago. DL was trying to quote me a higher rate than I was seeing. I called in, they could only see the higher fare, but Book With Matrix led me to the fare in question (which I was then able to book via Delta.com, much to my shock). Someone was probably querying inventory differently.

Of course, another time in the last few weeks I was also able to find a fare on Matrix and the agent was able to see it as well, so there was probably just a gremlin in the system.
