I just have a DXB-DOH-HKG ticketed by AA.

There is nothing mentioned about checked bag or even carry on bag on QR's ticket found on QR site, nor on QR itinerary.

Does that mean I too, have the same issue so many have suffered before?

Also is this specifically referred to checked bag, but not the carryon bag and personal item?

Update
On the chat now. Chat rep confirms there is NO checked bag allowance but claims since this is QR flight, QR policy governs....
I tried to explain to him to check with the rate desk, or help desk, this is an ongoing known issue that AA needs to reissue ticket to attach the bag allowance.
He kept insisting this is Qatar policy that "We do not reissue ticket to allow checked bags"
I kept asking him to check with his rate desk. He now said gave him 5 min to check...

I am not hopeful.

Sure enough, he came back insisted this is a Qatar operated flight hence Qatar baggage allowance applied. He did not understand the issue at all even after checking with somebody for several minutes. Came back with the same nonsense answer claiming whoever he checked with, told him the same.

Looking at QR Trip Summary online
There is a column called
Class /Checked baggage allowance
First is shown, but Checked baggage allowance is empty.

So it definitely has no checked bag allowance, and the chat rep confirmed it but insisted QR policy governs.... SIGH.

May need to open an account on X and go that route.
