Dear all,
I am trying to sort out an itinerary while trying to optimize my (low) Qmiles and Avios resources. I have come up with a somewhat creative solution but I am not sure whether it is actually feasible or would rather lead to the original ticket being cancelled entirely.

Basically, the itinerary would be A-B (return) via DOH whereby,

• A-B: regular economy ticket on QR.
• A-DOH: upgraded with Qmiles (provided there is space available).
• DOH-B: Avios booking biz. Yes, I am aware this would be a new ticket on the same flight. Would this be possible?

The other option I had thought about was to get 1. A-DOH roundtrip (and upgrade with Qmiles); and 2. DOH-B Avios ticket biz. However any roundtrip ticket to DOH for the dates I am looking at is extremely expensive.

Any suggestions / advice would be more than welcome. Thanks!
