The ITA Matrix tool was ridiculously helpful when dealing with my old company's corporate travel agent. They would invariably put me on some horrible flight schedule unless I used Matrix to find the best route and just give them the flight numbers to book. It also was great the one time I was 4 segments away from requalifying for platinum on AA and needed to make it up before the end of the year. That routing language is good when you need to stuff extra segments into a trip and have them be on a specific airline. Turned out the cheapest route was to have me go to Omaha (by way of Chicago) where I met a friend for lunch in the airport cafeteria and then hopped right back on a plane home.
