FYI - you can access most of ITA's routing language on Hipmunk, if you type :: after an airport code. The advantage of using us is we can make you a booking link to actually purchase the itinerary.
Good stuff. Saves me the time from matrix.itasoftware.com to go to the airline or booking site.
What about limiting it to fare basis? for example: sfo::/f bc=y atl::/f bc=y doesn't work. There another way?
Love what you guys do and will have to check on working there at some point.
