I'll wager you anything you like that the price list on the Matrix is also listed on the airline website. I am Not affiliated with them - just have used this software for many years and the price listed there is the lowest you will find - unless you get a charter flight just trying to fill up, last minute. I have never had a problem booking directly through the airline websites. The airlines from IND to MBJ are typically $1.00 cheaper than the lowest price for the exact flight you will find on Expedia, Travelocity, etc.
