Note that ITA Software (matrix.itasoftware.com) is *not* a booking agent; you can't book space through it. It's a technology demonstration for their actual product, which is the engine that they sell to airlines to power their web site booking engines. It functions as a trip planner, though, and is one of the best, if not *the* best. But even though you get full details of the flight and fare, down to the actual fare code and breakdown of base fare, fees, and taxes, as well as fare rules, there is no link even to the airline to book it; you have to do that manually and make sure that the flights/fares/rules exactly match what ITA generated. I have found that occasionally to be difficult, especially when ITA generates a routing that is not one that the airline generates in their direct flight/fare/route display for the itinerary. -- Michael C.
