Well, mine says QR909 & QR149. For example, with BA, there is a refuelling stop at SIN, everyone has to disembark and re-embark but it's considered as one flight and these two flights have the same flight code.

As told, I cannot find any availability if I search for two segments, SYD-DOH and DOH-MAD respectively, but only SYD-MAD gives some availability.
