Whole itinerary

I was originally looking at:
MPM-DOH-MAD-DXB-LHR-JFK-YVR-HKG-TYO-SIN-MEL-CPT
but kept getting the error between TYO ans SIN
I have in the past gotten the error when trying to select a codeshare instead of the operating carrier. If you saw the error when at the select flights stage, simply try a flight marketed by the operating airline.
