But with QF you can fly QF marketed on a range of operating airlines and still get QF status. But QF is not a good ffp:- just an example. QF ffp is not for you.

If you want on airlines that fly from Poland that makes it harder. BA may be the only option.

Look at AA and read about the "operated by" nor "marketed by". AA took away the 4 AA flight rule a few years ago.

The required mix of marketed and/or operated for status depends on the ffp.
