Finally, any ideas on how to maximize the point earning - given that I pay for my own flights

- when commuting weekly between Amsterdam and London? I guess flying LH with one stop in each direction should give me in 2400 points per roundtrip in Economy?
Thanks!
I have bought LH codeshare tickets many times.
You get BMI points, no matter if you buy the ticket from LH with LH-prefix.
The good thing is that you do not need to worry about Tiny fares and such.
Flying AMS-LHR via FRA or MUC you should probably get 2400 points return (1200 points each way).
But the cheaper tickets (below booking class B or H or so) do usually not allow transfers via FRA or MUC.
I have tried to book CDG-LHR on LH via FRA myself for the same reason (and to avoid BMI) but it ended up being quite expensive.
Almost all cheap/medium-priced tickets AMS/BRU/CDG-LHR booked through LH only allow travel on direct flights.
