Pleasure.

My upcoming trips;
I have oneway TK J WAW-IST-KUL this summer, and would like to use it for accumulating miles for redemption and/or *AG
Also planning a holiday trip to Male/Middle East this winter.

I am thinking of
1) go for A3, but they change the earning to only 100% for TK J. Also no mileages for most of my intra Europe flight.
2) Lifemiles or UA as they have buy miles promotions in case I don't have enough miles for getting award flight in C/F.

So what's your opinion? Should I go for A3/lifemiles/United? Or any any other options?

Thanks.
