On the qualification side there is a multitude of ways to the same level in the various schemes. The airlines use their programmes to incentive customers. Oneworld could be neutral and simplified. The airlines can still have their programmes and incentives, but Oneworld would be the benchmark and option for those who aren't loyal to one airline. This is possibly the impossible ask, but where my question sits. Where is the Oneworld standards for qualification.
