I’ll earn my first GUF2 in the next few weeks and so am new to the rules.

On a BA 125- ticket, is it possibly to use a GUF2 where part of the journey is codeshare on non-BA metal?

In my case, I’m looking to fly my parents-in-law from PER-DOH-LHR and back on a 125- ticket and wanted to know if it would be valid on the PER-DOG QR flights (BA codeshare).

Otherwise I’ll transfer Avios BA-> QR for full redemption if GUF2 not possible here.
