Where to credit miles from LHR-PVG-MEL RT in discount Y on MU?
A friend will be flying LHR-PVG-MEL roundtrip in discount Y (R and T booking classes) on MU metal.
She does fly that route occasionally (maybe twice a year) but usually chooses the cheapest fare.
Of interest would be miles that don't expire as quickly.
Where should she credit the miles? The goal would be to use the miles in the future for the the LHR-MEL route.
