This question shows my inexperience! Following some threads on this great site, I am going to do an LH RTW in Z rather than SK RTW economy/premium economy. Less than half way through the trip I will re-qualify for Eurobonus Gold. Can I then put the rest of the points in M&M or do I have to put all the points for the trip in the one FF account. Thanks for your patience!
Are you doing a Star Alliance RTW? It's usually booked in D.
You can switch bonus card for every flight so it's not a problem to change from Eurobonus och M&M half-way.
