Ok, so I've tried to search and just confused myself more! Please don't be too angry with me though if this has already been answered!
Like others I'm booked on the QR "Sake Fare" in November. I also have a couple of AA domestic sectors in May, so all I need for silver is the 4 BA eligible flights.
So - does a BA codeshare operated by Vueling count as "eligible"? Be much easier for me to do a couple of weekend trips from BHX or MAN than make my way down to LHR or LGW!
