I have been trying to book an award flight but keep getting an error. "This service is not available for the specified itinerary. Please check the User Hints below and re-specify your flight conditions.Please click here for itineraries and the number of routes that can be reserved."
Trying to book 1 business class for Chicago->Istanbul-> TPE. Then return TPE->Istanbul-> EWR. All via Turkish airlines. I can see the availability, but I am unable to book. Any thoughts?
