i'ma'bet their lawyers can argue the definition of "itinerary" in their favor. would be easy to support that "home" is not your destination, but rather your origin, that a round-trip journey may be ticketed at the same time and printed on one paper for convenience, but contains two itineraries.

but i'm not a lawyer, and would feel foolish arguing the meaning of "is" in court. i hope it works out for you, and wish you the best. but be prepared.
good luck!
