ITA Software
 

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

Well you could try something like Travelocity. But if you can't find a website to book it, just look for a travel agent that doesn't charge a fee. If you have an Amex card, call Amex travel.

Maybe if you are a AAA member, you could use one of their travel agents? (Just a suggestion; I have no idea if they are still free with membership!).

I usually find in these cases using Expedia's multi-city function works great in cases like this, just make sure when complete trips come up, choose the choose my own flights option and build the trip flight by flight.
