Maybe a final thing to consider - apparently just 60k miles are at stake, if used wisely having a value of about 600 Euro. But many uses such as buying SAF or donations to a good cause only give half that value, 2000 miles per Euro. Then any mileage run thrown in to save the miles should be really cheap, also given the uncertainties expressed above that the miles will be re-instated....otherwise you pay more as the value you (hopefully) get back. Or the flight you take should not be purely a mileage run but is useful in some way, e.g. holidays or a family visit.
