Hi all, maybe the master minds here have an idea:

I need to book a *A RTW, originating somewhere in Europe: Europe - ICN - OMA - ORD - JFK - FRA - Europe

I've been trying to plan this on the *A website, but despite the fact that I could book ICN - OMA (using a newITWMatrix search) for example ICN-xNRT-xORD-OMA (Asiana, ANA, United), the *A tool always tells me it can't make that routing.

Any ideas?
