I’m trying to transfer my Amex Membership Rewards points to Aeroplan and use them to book a direct flight from the US to Istanbul on Turkish Airlines. When I called Aeroplan, the agent said they couldn’t find any Turkish Airlines availability, but I can clearly see two daily direct flights operating on this route.
Does Aeroplan actually support Turkish Airlines bookings? Turkish is a Star Alliance member, so I assumed this would work and have seen done success stories. Is this a known issue with certain agents not knowing how to search partner availability? Or is there actually a block on TK redemptions that I’m not aware of?
