I erroneously cross-posted this question to OMNI. I apologize (there - and - here).

If ITA Software gives you a domestic US routing using two different airlines (and so you can't book yourself easily or even at all), what is the cheapest way to get the routing ticketed (My travel agent charges $50 a ticket, so for a family of four that's at least $200 which defeats the purpose of the great routing).

thanks
