That's awesome, but once you find an itinerary you want, how do you book the flight? Do you usually go to the individual airlines' websites and rebuild the itinerary by hand? Or do you send the 'fare construction' string over to a travel agent?

Depends on the flight, but I usually use a travel agent.

If it's a simple flight, I might use some airline website to book it, but most often for me it's some thing that you can't book at all on the airlines I use. I fly into small rural airports and they simply dot not exist on any major airline's websites.

I give the string to a travel agent and he is able to book the flight no problem.
