I've searched around but can't find a definite answer. CO allows one stopover and an open jaw on award ticket. Is it possible to use the open jaw with the stopover? E.g. JFK-IST (destination) IST-FRA (stop over) (open jaw) LHR-JFK. When I called (multiple times) I'm being told the computer won't price it. When I asked to have it priced manually I'm being told open jaw must be either at the origin or destination. Is that correct?
