Is there a flight search engine that will let me do a search of the form: Airport-to-any-airport but connecting through a specific airport? Often times A-B one way tickets are more expensive than A-B-C. In this case throwing away B-C segment is the better priced option. Of course, not making a habit of it so no worries getting caught. Does ITA routing language etc. cover this?

My specific example is a flight from CDG-FAI on the 23-Nov. One way ticket is $2100. Booking a return doesn't help much.

OTOH my colleague travelling BOM-FAI can get away with paying only $1000 and the irony is that the flight connects through CDG! Sigh. (I know I can't book this; my ticket would be cancelled as a no show from BOM)

Wondering if there are any (cheaper) routings that originate at CDG but would connect via FAI to any airport (I'd dump the last segment). Is FAI much of a transit airport at all?
