I've said it before, my TA is a star. Just spent an hour on the phone with them on this Saturday and they gave me a range of J options - cheapest, preferred carriers, stopover/no. Chinese carriers, other Asian (multiple), TK etc.
Decided to book TK ex SIN (connecting with my existing Award flights MEL-SIN-MEL), (
@MEL_Traveller will be pleased!) with almost identical timing to my existing QR flights; not the cheapest but not far off. Fully expect to cancel it, as I'm expecting QR to be OK in 3 weeks, and only US$150 to cancel. But if not, full refund from QR.
Have until Tuesday to pay/ticket and will keep looking for options.
