Successful booking (finally!). I used a pro account on Seats.aero to find these.
May 2024, 2 pax, J, SIN-IST
(SQ SIN-SGN, TK SGN-IST)
156,000 miles and US$50 booking fee
The website wouldn't complete the booking, but I used the chat on the website, and it was very efficient. The agent sent me the itinerary to confirm all details were correct, and I got a call for payment within 24 hours.
